ASF series

Summary

Product Identification

The ASF series filters are simple manual screen filters featuring a stainless steel housing. They are described as durable, economic, and easy to maintain.

General Features

• Stainless steel housing and filter cartridge.
• Interchangeable screens with several filtration degrees.
• No mechanical moving parts.
• Very durable and economic filtration choice.
• Easy to install, maintain, and clean/change cartridges.
• Low pressure loss.
• Can be equipped with an automatic drain valve and magnetic kit to capture particulate metal.

Operating Limits

• Max working pressure: 10 bar (145 psi)
• Max working temperature: 80 °C (176 °F)
• Max flow rates: Up to 1400 m³/h (6164 US gpm), with specific models ranging from 30 m³/h up to 1400 m³/h.
  • Flow rates are referred to a 100 µm filter screen, water with NTU < 1, and a temperature of 20°C.
  • Head loss data is available, also referred to a 100 µm filter screen, water with NTU < 1, and a temperature of 20°C. See the official PDF for head loss graphs.
