Custom Solutions for Drones & UAVs

Universal Air Filter specializes in custom products for various UAV applications

Drones and Unmanned Aerial Vehicles (UAVs) require careful thermal management of their batteries and protection from the elements. In flight, the rush of air can provide passive air cooling to mounted batteries, but allowing airflow to the batteries introduces a new set of challenges: keeping dust, rain, snow, and other environmental particles out of the battery terminal and UAV interior.

UAF offers a range of framed and unframed filters that can be custom made to the specifications of your UAV, allow for effective cooling of the battery while protecting it and the sensitive electronics inside the drone from environmental hazards. We protect batteries both in flight and from ground splashes / kick-up during belly landings.

UAF filters are designed to be cleanable, are manufactured in Sauget, Illinois, and can meet UL94, MIL-SPEC and other ratings as needed.  Our most popular filter solution for UAVs includes both our proprietary Quadrafoam™ media and a layer of hydrophobic mesh. The combination can be as thin as .125” / ~3mm, is very low weight, and has an initial resistance of .07 in.w.g. This material is also able to achieve a UL900 or UL94 HF-1 flame safety rating.

When pressure fit into a well-constructed enclosure, this media combination can help provide an IP44 level of protection for your UAV.


UAF supports full compliance with stringent industry standards:

  • NEMA
  • IP Ratings

UAF Filtration Products for Drone Air Filters


Quadrafoam Air Filters

Quadrafoam™ air filters offer low pressure drop, fire resistance, and the ability to capture large amounts of airborne dust in industrial enclosure applications.

Hydrophobic Mesh Filters

Hydrophobic Mesh air filters offer a water-repellant, low pressure drop media to reduce ingress of airborne mist and other liquids on enclosures deployed in harsh environments.

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.

Flex-Frame Air Filters

Flex-Frame air filters use flexible, flame retardant, polypropylene plastic. They are laser cut to spec allowing virtually any frame profile to meet the needs of the most challenging applications.
