Description

Air Maze Molded End Filter Part 4DA-007

Molded End Filters

• Rugged self-sealing polyurethane ends – not plastisol (PVC)
  • No bypass or cracking with age
• Textile media – not paper
  • Handles moisture, vibration, and abuse
• Genuinely cleanable
  • Practical & economical
• Exceptional performance
  • Lower delta p and longer life

More than 50 years ago, molded end filter elements challenged the worst of punishments in industrial and military services. Today, with synthetic rubber ends, they are still arguably the finest air/gas filters ever made.

Rugged Construction

Standard construction includes solid rubber (polyurethane) ends, heavy-duty perforated metal center cores, and radial pleated filter media jacketed with woven wire screen.  This screen jacket holds fins open, greatly improving flow capacity, service life, and durability. Textile media are well known for superior performance and clean-ability vs. fragile paper media. This industrial grade construction has been long proven to yield higher flows, longer life, and lower delta p.

Polyurethane Molded Ends

The filter media, support screens, and element cores are bonded together by the polyurethane end seals.  Our polyurethane is much more rugged and durable than lesser polyvinyl elastomers used by others.  It will not crumble in service as under-cured PVC can. PVC is as much as 50% plasticizer. When this plasticizer evaporates, PVC ends can crack and fail.

Production molds are carved from solid stock (no stampings) for exacting end seals. These seals stop dirt and resist most oils, solvents, moisture, or vibrational punishment. They can withstand continuous service to 200 F.

Option

Core & Wire – Center core material options include carbon steel, 304SS, 316SS, or electro galvanized expanded metal.  Thicknesses up to 11 gauge can be selected for high collapse/burst pressure requirements.  The standard woven wire support is epoxy coated aluminum, but 304SS, 316SS, and galvanized support screen is also available.

Filter Media – Our standard media is 10 micron polyester felt, but dozens of media options are available for particulate or coalescing applications.  Efficiencies vary from 750 micron down to 0.1 micron.

End Seals – Other end seal options include black PVC, oil and gas resistant PVC, white PVC (for use in processes related to food), and silicone RTV good to 500 F.  For high-heat and chemically aggressive applications, metal end designs are available with special potting and gasket material.

Size – Typical sizes include overall heights to 40 in, outside diameters to 36 in, and inside diameters from 1 in to 30 in.
