Filter: Model 654F: 8.25" [209.6mm] square x 0.50" [12.7mm] deep. All Kooltronic filters consist of a multi-layer grid of sturdy corrugated aluminum, securely held in a one-piece aluminum frame. Filters are required whenever air is drawn into an electronics enclosure. A non-drying adhesive coating traps a high percentage of particulate matter. These washable, reuseable filters are designed to last the life of the cooling unit. Replacements are available for those which become damaged or otherwise non-serviceable.
Filter Holder: Model 654HF: Precision-made heavy gauge steel construction. Can be mounted either internally or externally on enclosure using (4) .187" [4.7mm] dia. holes (see diagram below) Suggested use is on the intake (motor) side of the fan where it will add less than 0.75" [19.1mm] to the depth of the fan. Filter inserts easily.
Guard: Model 654G: Made of sturdy corrosion- protected wire, these guards comply with OSHA and UL safety standards. Suggested use is on blade side of fans and on motor side, if being used without a filter. Adds less than 0.75" [19.1mm] to depth of fan.
Caution: We strongly recommend proper guarding of fans to prevent serious injury.
