High Performance Bag Filter Applications
M5 & M6 Medium Grade Bag Filters
M5 & M6 Medium Grade Bag Filters for use in heating, ventilation and air conditioning systems (HVAC) where a moderately high standard of cleanliness needed. Also where a greater dust holding capacity is required than a panel filter can offer, whilst providing low resistance, the bag filters large pocket allows for this.
Medium Grade Bag Filters are also ideal as a pre-filter to higher efficiency bag filter systems. M6 is considered the minimum grade for kitchen supply air.
F7 F8 & F9 Fine Bag Filters
A high grade synthetic bag air filter for use in ventilation systems that require a high standard of cleanliness including offices, schools, hospitals and shopping centres.
Also where a greater dust holding capacity is required that a panel filter can’t offer, the High Efficiency Bag Filters large pocket allows for this whilst providing lower resistance.
The High Performance Bag Air Filter is designed to ensure long life between maintenance intervals.
High Efficiency Bag Filter Construction
Our High Efficiency Bag filters features synthetic media, each pocket is constructed from lofted synthetic micro fibre. Integral spacers prevent over inflation of the pockets and provide uniform air distribution throughout the media. The pockets are retained in a rigid galvanised header frame ensuring maximum stability in all applications.
