Custom Solutions
UAF’s team of dedicated engineers have experience designing protection for a variety of industries. We partner with enclosure manufacturers to offer a custom solution and meet UL, NEMA and IP requirements while allowing for necessary heat dissipation with direct air cooling.
Efficiency and filtration options are available at all levels with our media options, and our hydrophobic and salt fog solutions can improve designs by reducing louver profiles or bulky v-bank filters. Salt fog elimination options are available as well for coastline or marine environments and industries with corrosion requirements.
Core Enclosure Solutions
All length and width dimensions are fully customizable along with mounting options, gasketing, thru holes, pull tabs and more.
Mid-efficiency Quadrafoam and PET Hydrophobic mesh for a cleanable, NEMA 3R filter that carries a UL94 HF-1 flame rating
MERV 15 efficiency with a cleanable hydrophobic pre-filter. 2″ nominal and 3″ nominal thicknesses available for improved airflow for IP5X applications
Made with Telecom standards in mind, this IP65 filter is designed for harsh weather and eliminates salt fog. Pleat depth options are available based on air flow requirements
Why Direct Air Cool?
Lower Cost
Air Conditioners and Heat Exchangers create higher initial costs and are more expensive to maintain.
Energy Efficient
Direct air cooling is the most energy efficient cooling method as compared to Air Conditioning or Heat Exchanging.
Thinner Profile
Recessed filter fans offer a more streamlined look for the end product and reduce overall material usage.
Will DAC Work for my Application?
Our broad suite of media solutions includes electrostatic media, hydrophobic mesh, metal mesh, wire screens and more. For fan-cooled outdoor enclosures with critical components to protect and higher standards to meet, we recommend our PentaVent, Weather Resistant (WR) or Outside Plant (OSP) products. Technical data sheets including pressure drop curves, along with rapid prototype samples are available upon request.

UAF Filtration Products for Power Generation Air Filters
Weather Resistant Air Filters
MERV 15 efficiency with a cleanable hydrophobic pre-filter. 2″ nominal and 3″ nominal thicknesses available for improved airflow for IP5X applications.
PentaVent™ Filters
PentaVent™ is UAF’s thinnest outdoor framed filter offering at .5″ thick and can help your cabinet meet an IP44 or NEMA 3R rating without the use of louvers.
Outside Plant Filters
Custom Outside Plant Air Filters keep dust, water, wind driven rain and salt fog out of electronics enclosures that use fresh air and direct air cooling systems.
