Features

1 Removable outer frame design

2 High dust loading capacity

3 Washable media

4 Efficiency：G2/G3/G4/M5（EN779）。

Structure Description

1 Removable and firm frame design. The frame is made of fir aluminum alloy sheet with ABS plastic or aluminum alloy corner connectors to ensure its rigidness under harsh working environment. The outer frame is removable and recyclable.

2 The media is hold by rib supports for rigidness and uniform pleat shape. This ensures low pressure drop and high dust loading capacity.

3 Replaceable panel pre-filter is made of high quality polyester fiber which can be washed and reused for several times. It has a long service life as well as high dust loading efficiency and capacity. It can be used to prolong the service life of secondary or tertiary filters.

4 To fit clients’ requirement， Replaceable panel pre-filter comes with 1-inch thickness design (21、23、24mm), 2-inches thickness design（46mm）and 4-inches thickness design（96mm）. The 1-inch design is used in the panel structure while the 2-inches and 4-inches designs are used in the pleated structure.

Wide size are available.
