Series FH-400 Single Bag Filter Housing
VQ-FH400
Stainless steel single-bag filter housing with a swing-bolt closure and an internal restrainer basket, for coarse and medium filtration on process and utility lines.
- FLOW
- to 80 m³/h
- RATING
- 1 to 800 micron
- DESIGN PRESSURE
- 10 bar
- TEMPERATURE
- to +120 °C
Why it is specified
A filter housing is judged on how fast a bag can be changed and on whether the seal survives the change. This one uses a swing-bolt lid and an O-ring in a machined groove, so the bag comes out in under a minute and the seal stays where it belongs. Size 1 and size 2 bags, 1.4404 throughout.
Typical applications
- Cooling tower side streams
- Edible oil polishing
- Paint and coating transfer
- Pre-filtration ahead of cartridge stages
- Resin and adhesive lines
Options and executions
- Davit arm for the lid above DN80
- Differential pressure gauge with a switch contact
- Jacketed shell for viscous media
- Magnetic insert in the basket
- Material certificates to EN 10204 3.1
- Quick-release clamp closure in place of swing bolts
