INSTALLATION FRAMES

FRONT ACCESS FRAMES Front withdrawal frames are pre-drilled for alignment and ease of on-site assembly. They may be used as standard to house a variety of NFC air filtration products either singly or in tandem for pre and secondary filters, simply by provision of the correct size retaining clips. NFC front withdrawal frames are complete with seal and four retaining clips per frame.

Standard frame sizes: 610x 610x 75mm (actual) 610x 508x 75mm (actual) 610x 305x 75mm (actual) Non standard sizes are available to order. SIDE ACCESS FRAMES Side withdrawal frames are manufactured with two or three channels.

One channel to allow 'fixing' into an air handling or ductwork section. The second channel is to house the selected air filter type. Where two filters are required in tandem, a third channel is added. Each filter channel is fitted with a 'back seal' to reduce the risk of air by-pass. An end plate is provided to seal the assembly. Standard sizes are available in heights of 300mm and 600mm. Widths are from 300mm to 2400mm in increments of 300mm.

HEPA AND CARBON BASE FRAMES are produced singularly or in banks.

PURPOSE MADE HOUSINGS are supplied to accommodate any of the Nationwide Filter Company product range.
