Air Source Double Unit AFC / BFC

The difference between a triplex unit and a double unit is actually quite obvious — it is simply the addition of one related accessory. In a triplex unit, following the direction of the air inlet, the components are arranged as air filter, pressure reducing valve, and lubricator. The combination of an air filter and a pressure relief valve is called a pneumatic double unit. Since the main and driving cylinders of the air-boost product are separate, in the double-unit configuration the carbon-steel air-source double unit must lubricate the driving cylinder body. However, it is not a body without a pressure medium.

This pressure reducing valve keeps the air source stable and will not affect the boost product of the pneumatic booster (drive pressure 8.3 bar), thereby reducing damage to the pneumatic booster or booster equipment caused by sudden changes in air-source pressure. The filter is a device that purifies the air source and filters the moisture from the compressed air, thereby preventing moisture from entering the interior of the pressure pump along with the gas and extending its service life.

The lubricator filter can lubricate the driving part of the air-boost pump and lubricate the oiled components, thereby greatly extending the service life of the air pump.

From the above introduction we can see that a small double unit can bring great convenience to pneumatic and hydraulic booster pumps, and its price is also very reasonable, making it an excellent choice.
