AF-1600D Semi-Automatic Cartridge Gas Filling Machine

Q: What are the gas fill weight and accuracy of AF-1600D?

Gas fill weight is 150–300 g, with repeat filling accuracy within plus or minus 1 percent.

Q: How should the output of AF-1600D be calculated?

The specification gives the per-head rate of 3000–4000 cans per day. The machine has twin filling units, and actual daily output is limited by how fast the operator loads and unloads cans and by the leak testing rhythm. Confirm the figure with the factory before quoting it.

AF-1600D semi automatic aerosol filling machine

AF-1600D is a semi automatic aerosol filling machine built around three stations — vacuum evacuation, valve crimping and gas filling — equipped with two gas filling units and two booster pumps. It runs at 3000–4000 cans per day per filling head, with a gas fill weight of 150–300 g and repeat filling accuracy within ±1%. A semi-automatic water bath leak detector with temperature control completes in-house leak testing. It handles aerosol cans with the international standard 1-inch (25.4 mm) valve, can diameters of 35–65 mm and can heights of 70–330 mm, making it a practical crimping and gas filling solution for small-to-medium batches of butane and propellant cartridges such as portable camping stove gas cartridges.

1. Product Overview

Applications

Suitable products (per the factory equipment list):

Portable gas cartridges (fuel canisters for camping and cartridge stoves)
Portable gas and propellant canisters in the 150–300 g fill range
Similar small disposable aerosol and gas cartridges

The exact medium (butane, propane blends, DME, etc.) must be confirmed against the customer's formulation.

Suitable containers: Tinplate and aluminium aerosol cans with the international standard 1-inch (1" / 25.4 mm) can opening, can diameter 35–65 mm, can height 70–330 mm

Core Functions

Function	Description
Vacuum evacuation	One vacuum station removes air from the can to prepare for metered gas filling
Valve crimping	One crimping machine crimps the 1-inch aerosol valve
Gas filling	Two gas fillers (dual filling units) meter the fuel gas or propellant at 150–300 g with repeat accuracy ≤±1%
Booster air supply	Two booster pumps deliver stable, dual-channel pressurised supply for simultaneous filling at both stations
Water bath leak testing	One matching semi-automatic water bath leak detector (with temperature control) for finished-can leak testing

2. Key Advantages

Dual filling stations plus dual booster pumps: Supplied with two gas fillers and two booster pumps, so both filling units can run in parallel and output beats comparable semi-automatic machines with a single filling head.
Three stations in one line: Vacuum evacuation, valve crimping and gas filling are integrated. The operator only loads and unloads cans, and the full vacuum → crimping → gas filling cycle runs on one machine with a small footprint and fast transfer.
Consistent fill weights: Gas fill weight of 150–300 g with repeat accuracy ≤±1%, reducing the gas loss and safety risk that come with overfilling.
Built-in leak testing: A semi-automatic water bath leak detector with temperature control is supplied as standard, so finished cans can be temperature-controlled water bath tested in-house to verify seal quality before shipment.
Broad can compatibility: Suitable for can diameters of 35–65 mm and can heights of 70–330 mm, both customisable to the customer's can.
Universal valve: Works with the international standard 1-inch (25.4 mm) aerosol valve, so customers need no extra tooling or modification for valve format.
Transparent air requirements: The air source specification is stated up front — 0.8–1.2 MPa with maximum air consumption of 0.8 m³/min at 0.6 MPa — so customers can verify their compressor and gas supply before ordering.
Customized: Can diameter, can height and fill weight can all be tailored to the customer's can and medium.

4. Sales Tips & FAQ

Sales Tips

Positioning: Suited to customers running pilot or small-batch production of portable butane and gas cartridges. This machine is gas filling only — customers who also need liquid filling on the same frame should be offered four-station machines such as the AF4-1600A.
Must-ask before quoting: ① the medium to be filled (butane, LPG, DME, etc.) and its required filling pressure; ② target fill weight per can (to confirm it falls within 150–300 g); ③ can diameter and height (to confirm they fall within 35–65 mm / 70–330 mm or need customising); ④ whether the valve is standard 1 inch; ⑤ whether the semi-automatic water bath leak detector is required; ⑥ whether on-site installation is required.
Be clear about output: The 3000–4000 cans/day figure in the specification table is the per-head rate. Twin filling units raise theoretical output, but actual throughput depends on how fast the operator loads and unloads cans and on the leak testing rhythm — do not quote double output without factory confirmation.
Custom-built equipment: Images are for reference only. Machines are built to the customer's can and medium, and the final configuration and lead time are subject to contract.
Differentiation pitch: Lead with the two points — dual gas filling plus dual booster pumps, and the supplied water bath leak detector with temperature control. Most semi-automatic machines at this price point use a single filling head and ship without any leak testing step.

FAQ

Q1: Which operations does this machine perform, and what does the operator do? A: AF-1600D handles vacuum evacuation, valve crimping and gas filling, all machine-driven. The operator only loads and unloads cans. A semi-automatic water bath leak detector is also supplied for finished-can leak testing.

Q2: Can it fill liquids? A: No. AF-1600D is a gas filling machine for fuel gas or propellant only. The specification table lists a gas fill weight of 150–300 g and no liquid filling station. Customers who need liquid filling as well should look at four-station machines such as the AF4-1600A.

Q3: What are the gas fill weight and accuracy? A: Gas fill weight is 150–300 g, with repeat filling accuracy ≤±1%.

Q4: How should output be calculated? A: The specification table gives the per-head rate of 3000–4000 cans per day. This machine has twin filling units, and actual daily output is limited by how fast the operator loads and unloads cans and by the leak testing rhythm. Confirm the figure with the factory before quoting it to a customer.

Q5: Which can types and valves does it fit? A: It fits tinplate and aluminium aerosol cans with the international standard 1-inch (25.4 mm) can opening, can diameter 35–65 mm and can height 70–330 mm. Sizes outside this range can be customised.

Q6: What are the air supply requirements? A: Air source pressure 0.8–1.2 MPa with maximum air consumption of 0.8 m³/min at 0.6 MPa. The machine comes with two booster pumps to keep the supply stable.

Q7: What are the machine dimensions and weight? A: The factory quotation does not list the main machine dimensions or weight. This item is on the pending-confirmation list — please request it from the factory and add it in.

6. Workflow

Semi-automatic sequence (manual can loading, stations in series):

Operator loads an empty can
    ↓
① Vacuum evacuation station — air is drawn out of the can
    ↓
② Valve crimping station — the 1" aerosol valve is crimped in place
    ↓
③ Gas filling station ×2 — metered fuel gas / propellant fill (150–300 g, accuracy ≤±1%)
    ↓
④ Semi-automatic water bath test — temperature-controlled water bath leak testing (dedicated detector included)
    ↓
Operator removes the finished can

Station order follows the equipment list in the factory quotation (vacuum evacuation → valve crimping → gas filling → water bath testing); the actual on-site sequence should follow the factory SOP.

Air circuit: gas source (butane / LPG / DME, etc.) → booster pump ×2 → gas filling station ×2. The twin booster pumps hold both filling lines steady at 0.8–1.2 MPa, keeping parallel filling smoother and safer.

Power/air supply: compressed air source pressure 0.8–1.2 MPa, max air consumption 0.8 m³/min at 0.6 MPa.
