Universal Air Filter Element Service Instructions
Pleated Paper Air Filter Element Specifications:- High Quality industrial grade filter paper-pleated oven cured during production
- Oven cured plastisol end caps with molded sealing beads (larger sized have metal end caps and closed cell rubber gaskets
- Media efficiency: 99.5% on 2 microns; 97% on 1 micron
Because of the relatively low cost of the paper element, it is generally treated as disposable and replaced when dirty. However, the paper element can be cleaned and reused a number of times.
Water Cleaning: Rap gently to dislodge accumulated dirt, soak thoroughly approximately 15 minutes in warm water and mild detergent. Rinse thoroughly under low pressure water. Air dry - do not dry with compressed air.
Compressed Air cleaning: Carefully direct compressed air (100 psi maximum) through dry air filter element, opposite normal direction of flow. After cleaning, inspect carefully for holes or cracks. If damaged, replace element.
Pleated Felt Air Filter Element Specifications:
- Durable polyester felt media - pleated
- Oven cured plastisol end caps with molded sealing beads (larger sized have metal end caps and closed cell rubber gaskets
- Media efficiency: 99% on 10 microns
Pleated felt elements may be cleaned and reused a number of times. Follow the cleaning instructions for paper elements.
Wire Mesh Air Filter Elements Specifications:
- Galvanized wire-mesh media - corrugated construction
- Larger sizes have metal end caps
- For best efficiency, wire mesh elements must be treated with oil or oil-free adhesive
- May be cleaned and reused an indefinite number of times (limited by rusting and damage)
- Wire mesh elements are considered "roughing" filters and are not recommended for applications which require efficient filtration of fine particles. Approximate efficiency: 93% on 10 microns (with oil or adhesive treatment)
For best efficiency, wire air filter elements must be treated when new and after each cleaning. For oil-free adhesive, spray the element on both sides with Universal Oil Free Adhesive (P/N 81-0323), following the directions on the container. For oil treatment, dip the element in SAE 30-50 motor oil and drain thoroughly before using.
To clean wire mesh element, wash in solvent or warm water and detergent in a container large enough for complete immersion of element. Rinse completely, drain either air dry or use compressed air. After cleaning and drying, re-treat the element with oil free adhesive or oil as described above.
Time to change your filter element? A clean element should have a pressure drop of 1 to 3" of water column (w.c.). Filter elements should be changed when the pressure drop exceeds 10-15"w.c. of pressure loss. You may want to clean or replace the filter depending on the power usage of your machine. Remember, excessive pressure drop will cost you horsepower ($$$!).
Some other potential problems include:
- Excessive temperature rise on the blower causing blower failure
- Excessive horsepower absorbed by your drive (for instance v-belts which may cause pre-mature failure)
- Excessive horsepower on your motor causing overload and pre-mature failure)
