⚠️ Power & Air Requirements: This machine is an electric-pneumatic integrated unit (pneumatic actuation + electric control). It must be connected to a 220V / 50–60Hz power supply (power draw only ~100W) and to an air compressor with supply pressure 0.4–0.6 MPa. Difference vs. the F6 fully-pneumatic series: the F2 adds an electric control system for steadier filling cycles and more precise control; the F6 runs entirely without electricity and suits explosion-proof applications.
core Abstract
The F2 series is Wenzhou T&D's semi-automatic horizontal electric-pneumatic liquid filling machine (Pneumatic & Electric Integrated). It covers 8 models (F2-50/100/300/500/1000/2500/3000/5000) with filling ranges from 5–50 ml up to 500–5000 ml. The machine uses an electric-pneumatic integrated design — pneumatic actuation with electric control: it requires 220V/50–60Hz power (approx. 100W) plus an air compressor supply of 0.4–0.6 MPa. It is fitted with Airtac pneumatic components and fills at 10–40 cycles/min; the electric control keeps cycle timing stable with excellent batch-to-batch consistency. The frame is 201 stainless steel, and all product-contact parts are food-grade 304 stainless steel (316 stainless steel available on request). Piston-type volumetric filling delivers ±1% accuracy with bottom-close positive shutoff drip-free nozzles (orifice 3–12 mm selectable). Two trigger modes — foot pedal or automatic timer — let the operator switch between semi-automatic and automatic operation. The filler comes with a single filling head as standard; dual-head, 4-head or 6-head versions can be customized. Suitable for free-flowing liquids such as water, edible oil, juice, milk, alcoholic beverages, liquid medicine and detergents.

2. Key Advantages
Electric-pneumatic integration (Pneumatic & Electric Integrated) is the biggest selling point of this series — the first five advantages below all center on it.
- Electric-pneumatic drive — more precise control, steadier cycles. Electric control combined with pneumatic actuation keeps the filling cycle precisely timed by the electrical system. In long continuous runs the cycle stays consistent with excellent batch repeatability; filling speed is 10–40 cycles/min and can be adjusted to the production pace.
- Electric control timer — finer automatic mode settings. In automatic mode the fill interval is governed by the electric timer: fine adjustment, fast response — ideal for rhythm-based continuous production.
- Airtac pneumatic components. Taiwan Airtac cylinders and valves deliver stable action and long service life. They are available worldwide, so spare parts are easy to source and the customer's long-term maintenance cost stays low.
- Ultra-low power — minimal running cost. Total power draw is only approx. 100W (0.1 kW) and it runs on any standard 220V/50–60Hz outlet; electricity cost is almost negligible. Air consumption is on par with comparable pneumatic fillers.
- Simple to operate — connect and start. Connect power (220V) and air (0.4–0.6 MPa), and production can begin. The electric control panel is intuitive and new operators learn quickly.
- 201 stainless steel frame + food-grade 304 stainless steel contact parts; 316 available. The all-stainless frame and food-grade product-contact parts meet food-safety requirements as standard (304); product-contact parts can be customized in 316 stainless steel for stronger acid/alkali and corrosion resistance — suited to pharmaceutical, chemical and corrosive products. A stainless steel valve assembly resists corrosion and is easy to keep clean.
- ±1% filling accuracy + drip-free nozzles. Piston metering is stable and reliable; bottom-close positive shutoff nozzles eliminate dripping and stringing, keeping bottle mouths and the workbench clean and reducing product waste.
- 8 models cover 5–5000 ml; changeover at zero cost. Adjust the piston stroke to change the fill volume — no parts replacement needed; a spec change takes just 2–3 minutes.
- Horizontal, compact and lightweight. The horizontal body has a small footprint and weighs only 22–32 kg (net), so it fits on a tabletop, workbench or in an existing line and is easy to move.
- Food-grade silicone seals (rated 200 °C). Food-safe silicone O-rings as standard; corrosion-resistant rubber seals can be fitted when filling corrosive products.
- Semi-auto ⇄ auto switchable and multi-head expandable. Start with foot-pedal semi-auto operation; when volume grows, switch to automatic timer mode or upgrade the single head to a dual/4-head/6-head machine — no equipment replacement, no wasted investment.

Talking Points:
- Customer wants steady cycles and control precision → lead with this machine: electric-pneumatic control keeps cycles consistent in long runs for stable batch quality.
- Customer's workshop has stable power and is used to electric-controlled equipment → highlight the intuitive electric control panel, fine timer adjustment and quick learning curve.
- Customer has no power in the workshop, or fills flammable liquids such as alcohol/solvents (explosion-proof required) → cross-sell the F6 fully-pneumatic series: it runs with no electricity and is intrinsically safe for explosion-proof duty — the F2/F6 pair covers both types of customers so no order is lost.
- Customer fills multiple specifications → emphasize "adjust the stroke to change the volume — no parts change; one machine replaces several."
- Customer has no air compressor → proactively remind them: this machine still requires an air compressor (0.4–0.6 MPa) — offer to add one to the order so the machine can run on arrival.
- Customer needs higher output → steer them to a dual/4-head/6-head multi-head machine, or to automatic timer mode, emphasizing "start semi-auto, upgrade to auto + multi-head, without changing the machine."
- Customer handles pharmaceutical/chemical or corrosive products → promote custom 316 stainless steel contact parts — corrosion resistance sorted in one step.
- Trading terms (standard quotation wording): MOQ 1 unit; FOB Ningbo / EXW Wenzhou; T/T payment; goods in stock; heavy-duty carton packing with tools and spare parts included.
4.2 FAQ
Q1: Does this machine need electricity? A: Yes. The F2 series is an electric-pneumatic integrated unit: the electric control section requires a 220V / 50–60Hz supply (power draw only ~100W), while the filling motion is powered by compressed air, so an air compressor (0.4–0.6 MPa) must also be connected.
Q2: Do I need an air compressor? A: Yes. The machine uses pneumatic actuation with electric control, so it must be connected to an air compressor supplying 0.4–0.6 MPa. An ordinary small piston-type compressor (with an air receiver/tank) is sufficient; one can also be added to the order.
Q3: Is the machine explosion-proof? A: The F2 is an electric-pneumatic model (it contains electric control parts) and is not intended as an explosion-proof unit. If the workshop has explosion-proof requirements, or the customer needs to fill flammable liquids such as alcohol or solvents, please recommend the F6 fully-pneumatic series (no electricity at all; intrinsically safe, explosion-proof).
Q4: What are the filling accuracy and speed? A: Accuracy is within ±1% (piston-type metering — stable, no drift); speed is 10–40 cycles/min, and the filling speed is adjustable.
Q5: What liquids can it fill? Can it handle high-viscosity liquids or pastes? A: It suits free-flowing liquids: water, edible oil, juice, milk, alcoholic beverages, liquid medicine, liquid detergents, etc. For high-viscosity products or pastes (sauces, creams, ointments) we recommend our paste filling machine series.
Q6: Are the product-contact materials food grade? A: The frame is 201 stainless steel and all product-contact parts are food-grade 304 stainless steel, meeting food-safety requirements; 316 stainless steel can be customized (greater acid/alkali and corrosion resistance — suited to pharmaceutical, chemical and corrosive products). Seals are food-grade silicone (rated 200 °C).
Q7: Will it drip or string? A: No. The nozzle uses a bottom-close positive shutoff design — the discharge closes the moment filling ends, guaranteeing drip-free operation. Nozzle orifices can be selected within a 3–12 mm range.
Q8: Is changing the fill volume troublesome? A: Not at all. Within the model's range you simply adjust the piston stroke to change the fill volume — no parts replacement needed; a changeover takes only a few minutes. Ideal for multi-specification, small-batch production.
Q9: Can it run fully automatically? What if I need more output later? A: Yes. The machine supports both foot-pedal (semi-automatic) and automatic timer (automatic) modes and can be switched at any time. For higher output you can order a dual (2-head), 4-head or 6-head multi-head version (one cylinder per head) — no machine replacement needed.
Q10: What are the MOQ, delivery time and warranty? A: MOQ is 1 unit; the factory keeps goods in stock for fast dispatch; export packing is a heavy-duty carton, one machine per case, with tools and spare parts included. The machine carries a 1-year warranty (free repair or part replacement for non-human damage during the warranty period; international freight borne by the customer), with lifetime maintenance service after the warranty period.
