Air Treatment Components / GA Series Air Preparation
13 AirTAC series for original sourcing, model quotation, replacement matching, or China-source alternative review when accepted.














The GA series represents modern compact air treatment units comprising GAF filters, GAR regulators, GAL lubricators, and integrated GAFC combos. Proper FRL sizing prevents system pressure drop and protects pneumatic cylinders from moisture corrosion.
| Unit / Combo | Port Thread | Filtration Rating | Max Flow (L/min) | Regulating Range | Drainage Configuration |
|---|---|---|---|---|---|
| GA200 Series (Mini) | 1/8", 1/4" BSPT / G | 40 μm (5 μm option) | 550 ~ 1,100 L/min | 0.05 ~ 0.85 MPa (0.5~8.5 bar) | Manual drain / Differential drain (Semi-auto) |
| GA300 Series (Standard) | 1/4", 3/8" BSPT / G | 40 μm standard, 5 μm fine | 1,800 ~ 2,600 L/min | 0.05 ~ 0.85 MPa | Automatic float drain / Differential drain |
| GA400 Series (High Flow) | 3/8", 1/2" BSPT / G | 40 μm / 5 μm sintered element | 3,500 ~ 4,500 L/min | 0.05 ~ 0.85 MPa (Max 1.0 MPa) | Automatic float drain (high volume collection) |
| GA600 Series (Heavy Duty) | 3/4", 1" BSPT / G | 40 μm brass / PE filter | 7,000 ~ 9,500 L/min | 0.05 ~ 0.85 MPa | Main airline drop, centralized machine headers |
40μm is the general factory standard for standard actuators and valves. For precision proportional valves, air bearings, or delicate instrumentation, a 5μm filter followed by a 0.01μm coalescing oil-mist separator is mandatory.
Pull up to unlock, rotate clockwise to increase secondary pressure, counter-clockwise to reduce, and push down to lock. Built-in internal relieving diaphragm automatically exhausts downstream overpressure.
Manual drain requires periodic operator discharge. Differential drain automatically expels moisture whenever the line is depressurized. Float-type auto drain discharges continuously whenever the water level rises.
GA series bowls are molded from high-impact polycarbonate encased in a steel or aluminum protective cage. Avoid contact with synthetic compressor oils containing esters or chlorinated solvents.
If your downstream cylinders use modern factory-lubricated seals and require oil-free air, use GFR (Filter-Regulator 2-in-1). If operating air motors, high-speed pneumatic grinders, or older heavy machinery that requires continuous lubrication, use the GAFC combo with lubricator.
Build your pneumatic circuit with complementary components. Confirm dimensions and operating conditions before selecting a combination.
