Clean Air Filter Replacement Anhydrous Ammonial Filters remove dusts and organic vapors before they enter your cab

Unlike standard cab filters that have only a paper-like medium to trap dusts, this three-stage Clean Air Filter Replacement Anhydrous Ammonia Filter combines dust filter mediums (Stage 1) with activated charcoal (Stage 2) which adsorbs anhydrous ammonia and traps pollen and molds. A final filter (Stage 3) reduces the amount of ammonia fumes entering your cab, so you breathe cleaner air. Each filter is housed in a durable metal case and is designed to fit snugly in your tractor cab with no modification. Replace filters annually or when you begin to taste or smell anhydrous ammonia.

Note: Custom filters may be available, on a special order basis, for Anhydrous Ammonia (NH3). Please call us and we will check for you (4-week lead time).

How to Order Your Filter: Identify your tractor or sprayer model from our updated and expanded list, cross check against our dimensions and manufacturer’s part number and specify GEMPLER’S item number.
