Disposable Polyester Filtration for Electronics, Telecom, and Industrial Equipment

High dust arrestance, low pressure drop, fire resistant disposable media

Polyester air filters provide high dust arrestance at low pressure drop, making them well suited for electronics, computer, telecom, datacom, and medical equipment where disposable filtration is the preferred approach. UAF polyester filters use a non-woven, non-migrating synthetic media that delivers up to 90% ASHRAE dust arrestance.

All models are flame retardant and listed UL 94 HF-1, meeting requirements for NEBS compliant telecom applications and motor vehicle installations. Available as framed filter assemblies or cut-to-size filter pads.

Polyester Air Filter Specifications

Polyester air filters are ideal for telecom, medical, power gen, and many other industrial and commercial products.  Polyester air filters perform with a high degree of dust arrestance when installed in electronics, computer and HVAC equipment where disposable filters are most appropriate. Polyester air filters have been specially designed for equipment where space is limited.

Expanded on our specially designed Uni-Grid equipment, using .040″ thick, 3000 series aluminum. Uni-Grid expanded aluminum is approximately 85% open to lower resistance. Polyester filters use Uni-Grid support on both sides.

Frequently Asked Questions

What is polyester filter media?

Polyester filter media is a non-woven, non-migrating synthetic material used in disposable air filters. It provides high dust arrestance at low airflow resistance and is flame retardant, making it suitable for electronics, telecom, and medical equipment.

Are polyester air filters reusable?

No. Polyester air filters are designed as disposable filters and should be replaced when dust loading increases resistance beyond acceptable levels. For applications requiring a washable, reusable filter, UAF offers foam and metal mesh alternatives.

What standards do UAF polyester air filters meet?

UAF polyester filters are listed UL 94 HF-1 and UL 900 Class 2. They meet Telcordia NEBS GR-63-CORE requirements for telecom applications and are RoHS and REACH compliant.

What sizes are available?

UAF manufactures polyester air filters in custom dimensions. Media is available in 0.50″ (UFM-50) and 1.00″ (UFM-100) thickness, with frame thicknesses ranging from 0.30″ to 0.88″ depending on model.
