Filter Regulators

For optimum system air consumption and reduced maintenance

Filter RegulatorsFilter Regulators are recommended for each pump at the wellhead to economize on system air consumption, allow control of pump flow rate, and reduce service needs caused by air system debris and contaminants.

These high quality filter regulators are coated on the inside to prevent corrosion from condensed moisture.

All QED well caps and flanges include mounting provisions for these filter regulators, and other mounting options are available.

Compressor Sizing

A compressed air supply is required to power AutoPumps. Estimation of the fluid flow rates and air consumption of the AutoPumps and sizing of the fluid lines, air lines, and air compressor involves a number of factors. Our application specialists are ready to assist you.

The flow rates and air consumption for the AutoPumps can be compared by using the charts provided in the specs of each AutoPump model. The flow rate and air use curves are based on pumping to atmospheric pressure at the wellhead, and do not take into account any liquid piping system backpressures due to elevation changes or fluid friction.

Finally, there are some initial guidelines for air compressors. Most importantly, follow all application guidelines of the compressor manufacturer. A piston compressor may be a start/stop type or a constant run type. The tank (receiver) must be large enough, particularly for the start/stop type. The motor should not turn on more times an hour than recommended by the manufacturer. And start/stop compressors are typically assigned a 50% maximum duty cycle, meaning that the compressor is sized to provide twice the maximum air demand of the entire AutoPump system.

Rotary screw compressors are designed for constant operation, and so are sized to just slightly exceed the maximum air supply requirement; it is recommended that rotary screw compressors not be grossly oversized because some types may be damaged by continued operation at low partial capacity.
