At $23.00 per unit for 10 and $22.60 at 2,000, the UAH34A hardware—not its narrow tier spread—should drive the order. A 135W vacuum sealer is an external food-packaging appliance that evacuates a bag before sealing its edge; this model pairs a 30cm bar with 60–95kPa dry suction, dual pumps, and roll storage.
// 01 — Key takeaways
The listed seal width matches the built-in 30cm × 5m roll compartment and sliding cutter.
The dry-suction range is separate from the listed wet range of -1 to 65kPa.
Dual pumps feed a listed flow range of 4–8L/min ±15%.
The lowest current catalog price is the 2,000-unit tier; the 10-unit tier is $23.00.

// 02 — Decision
What should decide the UAH34A shortlist?
The UAH34A belongs on a shortlist when a buyer needs 30cm bag compatibility, integrated roll handling, and separate dry and wet suction ranges in one countertop unit. Its 135W rating alone does not predict seal quality; the seal bar, flow range, bag choice, and duty pattern must be read together.
What is an external vacuum sealer?
An external vacuum sealer draws air from a bag while its open edge sits across a heating strip, then closes that edge with heat. It differs from a chamber machine, which places the whole bag inside a chamber. The UAH34A also connects to compatible external containers through its supplied hose.
How much vacuum pressure is enough?
Pressure is useful only beside flow, bag construction, and product shape. The UAH34A lists 60–95kPa for dry loads and -1 to 65kPa for wet loads. The range gives the controller room to handle different modes; a smooth bag mouth and continuous seal still determine whether the package holds.
Why do roll storage and a cutter matter?
A 30cm × 5m roll compartment keeps bag material with the machine. The sliding cutter lets an operator set bag length around each product, while the 30cm bar closes the open end. That layout removes a separate cutting station and reduces loose tools on a food-prep counter.
// 03 — Specifications
Which specifications matter for a 30cm sealer?
Read the UAH34A as a 100–240V, 135W external sealer with a 30cm sealing width, 5mm wet and 7mm dry heating-strip settings, 4–8L/min ±15% flow, and separate suction ranges. The purchase specification should name the intended mode, bag, voltage label, and acceptance method.
UAH34A specification sheet
Catalog record · 2026.08
| Specification | UAH34A | Why it matters |
|---|---|---|
| Material | ABS | Defines the housing construction |
| Rated power | 135W | Electrical load for the listed platform |
| Voltage | 100–240V | Supports export-market voltage ranges |
| Sealing width | 30cm | Sets the listed maximum bag-mouth width |
| Heating strip | 5mm wet; 7mm dry | Separates the listed wet and dry settings |
| Dry suction | 60–95kPa | Rated range for dry-mode operation |
| Wet suction | -1 to 65kPa | Rated range for wet-mode operation |
| Flow rate | 4–8L/min ±15% | Describes the listed air-moving range |
| Included accessories | Vacuum bags and external hose | Supports bags and compatible containers |
What does 30cm change for bag selection?
The 30cm figure is the maximum listed sealing width, not the filled volume of a bag. Buyers should place the intended bag mouth flat across the bar and leave the product clear of the sealing area. The built-in roll supports custom lengths, but width remains fixed by the bar.
Why are dry and wet ratings separate?
Dry and wet loads behave differently at the bag mouth. Moisture can travel toward the seal as air leaves, so the UAH34A provides distinct ranges and heating-strip settings. Its detachable water tray catches drawn liquid, but the unit remains an external sealer rather than a chamber machine for liquid-heavy packs.
Which controls remove operator steps?
The illuminated touch panel, automatic cover closing, external-vacuum function, sliding cutter, and detachable tray place the common actions on one machine. A silicone sealing ring and constant-temperature heating strip support the closing stage. These features matter where several operators must repeat the same sequence with limited bench space.
// 04 — Comparison
How does UAH34A compare with two fetched models?
Among the three fetched models, UAH34A sits between a lower-priced 65kPa platform and a 220W model built for heavier cycling. UAH27GX shares its 30cm width and roll handling. UAHFW15 uses a 29cm bar, 80kPa suction, an automatic nozzle, and a catalog rating of 500 seals per day.
| Model | Power | Suction | Seal and workflow | From $/unit |
|---|---|---|---|---|
| UAH34A Featured | 135W | Dry 60–95kPa; wet -1 to 65kPa | 30cm; roll storage; cutter; dual pumps | $22.60 at 2,000 |
| UAH27GX | 120W | 65kPa | 30cm; roll storage; cutter; six modes | $12.20 at 5,000 |
| UAHFW15 | 220W | 80kPa; 12L/min ±15% | 29cm; automatic nozzle; liquid extraction | $56.00 at 500 |
When does UAH27GX make more sense?
UAH27GX fits a price-led household line that still needs a 30cm bar, built-in roll storage, a cutter, and external-hose vacuuming. Its fetched record lists 120W, 65kPa, 4L/min ±15%, and prices from $13.00 at one unit to $12.20 at 5,000.
When does UAHFW15 make more sense?
UAHFW15 targets a higher-duty workflow. Its fetched record lists 220W, 80kPa, 12L/min ±15%, an extended automatic suction nozzle, a filtered liquid-extraction container, and operation up to 500 seals per day. It carries a single $56.00 tier at 500 units.
Where does UAH34A earn its place?
UAH34A combines the widest dry-suction range in this comparison with a 30cm bar, dual pumps, roll storage, and a touch panel. It suits a buyer who wants more headroom than the 65kPa model without moving to the UAHFW15 nozzle system and its higher catalog price.
A buyer should choose the bag, load, and daily cycle first; wattage and peak pressure only become useful after that operating brief is fixed.

// 05 — Pre-order test
What should a buyer test before the PO?
A pre-order test should reproduce the intended bag, food geometry, moisture level, and sequence of repeated cycles. The result is not a single peak-pressure number. It is a clean seal across the full bag mouth, stable air removal, controlled liquid movement, and a workflow operators can repeat without extra tools.
Inspect seal continuity before suction claims
Run the intended bag across the full 30cm bar and inspect the cooled seam for channels, folds, or food residue. Repeat with the dry and wet settings that the line will use. A continuous seam is the first acceptance point because retained vacuum depends on the closed edge.
Record cycle behavior on dry and moist loads
Use fixed bag dimensions and a repeatable fill position. Record air-removal time, seal completion, and any liquid reaching the detachable tray. This separates bag and loading effects from the machine response and shows whether operators can keep the sealing zone clear during a normal run.
Run the complete roll-handling sequence
Load the 30cm × 5m roll compartment, pull a set length, use the sliding cutter, close one end, fill the bag, and finish the pack. The sequence tests the feature that distinguishes this model from a sealer that requires a separate roll dispenser and cutting surface.
// 06 — Commercials
What do the price tiers and carton data show?
The current UAH34A catalog spans $23.00 at 10 units to $22.60 at 2,000, a difference of $0.40 per unit. Freight planning changes more than the listed unit price across that range: each export carton contains 10 units, measures 50.5 × 44.5 × 42.2cm, and weighs 17kg gross.
How do the catalog tiers move?
| Quantity | Catalog price per unit | Change from 10-unit tier |
|---|---|---|
| 10 | $23.00 | Baseline |
| 500 | $22.90 | -$0.10 |
| 1,000 | $22.80 | -$0.20 |
| 2,000 | $22.60 | -$0.40 |
The tier table is the current catalog record. Logo work, retail packaging, accessories, destination documents, and freight belong in the final quotation rather than being inferred from the base unit price.
What does one export carton contain?
| Packing item | Catalog value | Planning use |
|---|---|---|
| Product size | 39 × 16 × 6.5cm | Counter and display planning |
| Packaged unit | 43.5 × 9.9 × 20.3cm | Retail-pack and shelf planning |
| Export carton | 50.5 × 44.5 × 42.2cm | Freight cube input |
| Carton quantity | 10 units | Master-carton count |
| Carton gross weight | 17kg | Handling and freight input |
Which order terms belong in the quote?
The standard customized-order MOQ is typically 100 units, while smaller trial orders are available on request. Bulk production is listed at 15–30 days after deposit, with trial units at 3–7 days. Terms include FOB China, EXW or CIF, 30/70 T/T, and Alibaba Trade Assurance.
// 07 — Buyer fit
Who is the UAH34A built for?
UAH34A fits distributors and private-label programs that want a feature-led countertop sealer: 30cm roll handling, a cutter, touch controls, dual pumps, wet and dry modes, and an external hose. It is less suitable when the brief demands chamber packing of liquids, a bar wider than 30cm, or a published 500-cycle daily rating.
Distributors and retail appliance lines
The model presents clear shelf features without requiring separate roll hardware. Its 100–240V input supports several voltage markets, while logo, color, packaging, and specification customization are available through OEM and ODM orders. The purchase order should state the destination cord, plug, label, and packaging artwork.
Hotels and light food-prep stations
A hotel breakfast or prep area may value custom bag lengths, a detachable tray, and a compact external format. The model can handle meat, fish, produce, and dry goods when paired with suitable bags. Daily volume should come from the station workload and the pre-order cycle test, not from wattage alone.
When should a buyer choose another format?
Choose a chamber machine when liquid-rich packs are the core workload. Choose a wider model when the open bag edge exceeds 30cm. Within this fetched range, UAHFW15 is the documented high-cycle option: its record names 24-hour use up to 500 seals per day and an automatic suction nozzle.
// 08 — Manufacturing
How we manufacture the UAH34A
Guilin Use at Home Technology Co., LTD controls the UAH34A path from private-mould housing through pump and control-board work, seal testing, packing, and after-sales support. The process matters to a B2B buyer because appearance, electrical configuration, package artwork, inspection criteria, and warranty terms can be tied to one factory order.
In-house tooling and private mould
The ABS housing uses a private mould. In-house tooling keeps panel fit, roll-compartment alignment, and external finish under the factory team, while OEM programs can specify color, logo, control labels, and retail packaging.
Pump and PCBA burn-in
The dual-pump assembly and control board go through powered burn-in before final assembly. This stage exposes early electrical or control faults before the touch panel, automatic cover, heating strip, and external-vacuum path are assessed as one system.
Quality control and seal testing
Line inspection covers air movement, mode response, heating-strip operation, seal continuity, cutter travel, tray fit, and hose function.
CE, RoHS, and 12-month warranty
CE and RoHS are the named export compliance marks for this workflow. The UAH34A carries a 12-month warranty. The order file identifies the destination-market document set and gives the buyer one route for manufacturing-defect claims.
// 09 — Food safety
Does vacuum sealing make food shelf stable?
No. A vacuum sealer removes air but does not make perishable food shelf stable or replace temperature control. USDA FSIS advises keeping perishable vacuum-packaged food at 40°F or below or frozen at 0°F. The FDA Food Code treats many retail reduced-oxygen processes as controlled operations with defined safeguards.
What is vacuum packaging?
USDA FSIS packaging guidance explains that vacuum packaging removes air from a package and creates a vacuum inside. That can slow oxygen-driven quality changes. It does not sterilize food, and the sealer specification does not determine storage temperature or safe holding time.
Why does low oxygen change the hazard?
Low oxygen slows some spoilage organisms but can favor hazards that grow without oxygen. In its answer to whether botulism can occur in vacuum-packaged food, USDA FSIS says refrigeration or freezing remains necessary for perishables and vacuum packaging is not a substitute for safe shelf-stable processing.
What should a commercial buyer document?
Separate the equipment file from the food process. The equipment file covers bags, modes, seals, cleaning, and maintenance. The food plan covers product hazards, temperature, labels, shelf life, and records. Food-service operators can use the FDA Food Code 2022 with their local authority when setting reduced-oxygen controls.

// 11 — Conclusion
Conclusion: when UAH34A belongs on the order
The UAH34A vacuum sealer belongs on the order when a buyer values 30cm roll handling, 60–95kPa dry suction, dual pumps, wet and dry control, and a compact external format more than the lowest entry price. Its narrow tier spread makes bag trials, workflow fit, packing data, and destination requirements the decisive buying evidence.
