Fourpeak Filters

    High-performance Deep Bed Filter
    General Purpose Air Filter
    Cost Effective

The Fourpeak filters are a high-performance deep bed filter available in standard and reverse flow models, providing high capacity with intermediate efficiency. The high performance is obtained through a multi-pyramidal configuration giving a maximum of filtering area without excessive depth in the direction of airflow.  

The design of the Fourpeak filters are registered and patents have been granted. The metal frame and all wire media supporting frames are powder coated or galvabond to prevent corrosion and to provide a smooth, snag-free media supporting surface. Several types of alternate media, both gel-coated and dry, are available. The gel-coated media are adhesive impregnated while dry media are  

operated without adhesives. All media are of the synthetic type, made from graded fibres and bonded. They are moisture, fire and fungus resistant and will not shed fibres into the clean  

air stream. 

Offering better performance than roll type and metal viscous filters, its multi-pyramidal configuration gives a maximum of filtering area without excessive depth in the direction of airflow. It is available in both standard and reverse flow models. 

Construction 

The standard airflow model consists of three basic parts: 

(1) a mounting frame, 

(2) an inner wire basket, 

(3) a media kit. 

The mounting frame is constructed of steel material. Two diagonal wires welded to the back of the frame rest in the formed media basket which is sewn to shape. The inner frame is of fabricated wire construction, incorporating wires that fit into the peaks of the media, thereby holding it’s shape. 

The all-wire inner-frame incorporates handles to facilitate removal. Formed clips affixed to the inner frame hold the inner frame securely in place. 

Performance Testing 

All filters tested to AS1324.2 Air Filter Performance. Test laboratory is accredited by the National Association of Testing Authorities, Australia. Accreditation number 13213. Performance tests are conducted at least once every 5 years within a controlled environment in accordance with NATA and Australian Standards requirements.
