Compressed Air Dryer Filter For Food Industry

oil separator filter compressor Characteristics

When the filter is blocked or the filter cake is too thick, the backwashing and regeneration cleaning process is activated to restore the filter's working performance. The system automatically switches the fluid flow direction, letting clean filtered fluid flow backward from the outlet to the inlet, scouring the filter medium and filter screen at a higher pressure. The reverse high-speed fluid impacts the filter cake and intercepted impurities, detaching them from the medium surface and discharging them through the sewage outlet. During backwashing, auxiliary methods such as air scrubbing or ultrasonic vibration can be combined to enhance the cleaning effect, thoroughly removing stubborn impurities inside the medium pores. The backwashing time and intensity are controlled by a program to ensure thorough cleaning without damaging the filter medium. After cleaning, the pressure difference returns to the normal range, the filter resumes forward filtration, and this regeneration process greatly extends the service life of the filter element and reduces operating costs.

This series of precision filters, the filter element production adopts the technology of American HANKISON company.

The filter element accuracy is based on ISO8573.

It should be specified when ordering. The processing capacity under different pressure conditions should be corrected according to the coefficient in the correction coefficient table.

To extend the service life of filters and maintain optimal performance, we provide scheduled regular maintenance and inspection service. Professional technicians perform periodic checks on key components such as filter housing, sealing rings, pressure gauges, flow meters, and automatic backwashing devices. They clean accumulated dirt, replace worn parts, test system tightness, and record operating data to form a maintenance report. Regular maintenance prevents sudden failures, reduces blockage risk, and keeps filtration efficiency stable. This proactive service helps users avoid costly emergency repairs and ensures long-term reliable performance of the filter equipment.

1. Q: What is the startup procedure?

A: First run air for 5 minutes, then power on; shut down: power off first, then close air supply.

2. Q: Is moisture at the outlet normal during startup?

A: Yes, normal; stabilizes after 5–10 minutes of pre-cooling.

3. Q: What parameters should be monitored during operation?

A: Refrigerant high/low pressure, inlet/outlet temperature difference, drainage, dew point.

4. Q: Normal refrigerant high pressure?

A: Air-cooled: approx. 1.2–1.8 MPa; water-cooled: approx. 1.0–1.6 MPa.

5. Q: Normal refrigerant low pressure?

A: Approx. 0.35–0.55 MPa.
