Pleated Panel Filters

Mod ls E35-xxxxx

General

Flanders E35 extended surface pleated filters are designed to operate in most installations. Available in 1”, 2”, and 4” nominal thickness, these filters have an average atmospheric dust spot efficiency range of 25-30% per ASHRAE Standard 52.1 test methods. E35 filters offer greater efficiency and service life than disposable filters, pad and frame systems, or metal washable filters. The overall design of this product makes E35 filters the accept- ed choice in applications requiring high perform- ance and extended service.

These filters are suitable for variable air volume systems. Operating face velocity ranges are from 0 to 500 fpm for 1” and 2” filters, and from 0 to 625 fpm for 4” filters. Each filter contains 11 pleats per lineal foot. E35 filters are UL 900 Class 2 listed.

Versatility

Most heating, air conditioning, or ventilating sys- tems can be upgraded with the use of E35 filters in place of existing flat panel types. The inherent strength of the filter allows for easy changeout as it will not collapse, warp, or bend in normal service.

E35 filters are available in a wide range of sizes and will fit most commercial and industri l inst lla- tions with little or no system modific tion. Fasteners are available to adapt the E35 filter to existing filter banks.

Installation Considerations

E35 pleated filters are sui able as primary filters and can be installed in Type 9 Holding Frames, K- Track Framing Module , Surepleat Side Access Housings and similar exi ting hardware. They may be used as prefilters for Flanders Precision Pak, PrecisionCell and Rigid-Air filters in these framing systems and in Sureseal Side Access Housings.

Construction

E35 filter fr mes re constructed from moisture resistant chipbo rd. Perforated steel support grilles on the upstream and downstream sides provide extra rigidity and strength. The entire unit is sealed to insure a positi e media-to-frame bond, eliminat- ing t e possibility of air bypass. The filter media is

aigh loft reinforced non-woven cotton/synthetic blend. It is continuously laminated to an expanded metal grid on the air leaving side to provide pleat stability throughout the life of the filter and to pre- vent media flutter while in operation. The E35 V we ge pleat allows for total media usage and pro- vides maximum airflow and dust holding capacity.

Important Featur s

•V-wedge pleats minimize end losses and reduce pressure drop.

•Expanded metal gr d prevents media flutter while in operation.

•Perforated steel support grilles strengthen the frame.

•Filt r m dia pack is sealed to eliminate air bypass.

•Average ASHRAE efficiency is 25-30%.
