G3 to F9 Air Filtration Panels for Commercial and Industrial HVAC Systems

Skytech Ultrafab HVAC Filter Panels provide reliable coarse, medium, and fine air filtration for heating, ventilation, and air-conditioning systems in commercial buildings, hospitals, cleanrooms, and industrial facilities. Available in G3 to F9 efficiency grades per EN 779 and ISO 16890 standards, the panels are manufactured from synthetic, glass fibre, or electrostatic media in rigid and pocket configurations for all standard AHU frame sizes. Our filters deliver low initial and sustained pressure drop, long service intervals, and compliance with ASHRAE 52.2, EN 779, and ISO 16890. Custom sizes and grades are available on request.

What Are HVAC Filter Panels?

HVAC filter panels are flat or pocket-type air filtration elements installed inside air handling units (AHUs), fan coil units, and ventilation ductwork to remove airborne dust, pollen, mould spores, and fine particulates from supply and return air streams. They are classified by their filtration efficiency — coarse grades (G3–G4) capture large particles such as lint and pollen, medium grades (M5–M6) capture fine dust, and fine grades (F7–F9) capture sub-micron particles. Selecting the correct grade balances indoor air quality requirements against energy consumption and filter service life.

Features and Benefits

• Wide Efficiency Range: G3 through F9 panel filters in a single product range — coarse pre-filters, medium-grade supply air filters, and fine-grade downstream panels all available from one supplier
• Low and Sustained Pressure Drop: Synthetic and glass fibre media selected for low initial pressure drop that remains stable over the filter service life — minimising AHU fan energy consumption
• Rigid and Pocket Configurations: Rigid flat panels for standard AHU filter banks and extended-surface pocket panels for high-capacity systems requiring longer service intervals
• Electrostatic Media Option: Electrostatically charged synthetic media grades for enhanced fine particle capture efficiency without the pressure drop penalty of pure mechanical media
• Standard and Custom Sizes: All standard AHU panel sizes (287×592, 490×592, 592×592 mm and equivalent) in stock; custom dimensions and depths produced to order
• Compliance Ready: Filter panels manufactured and tested to EN 779, ISO 16890, and ASHRAE 52.2 standards — efficiency classification certificates available for building regulatory compliance

Technical Specifications

Applications

• Commercial HVAC: Supply and return air filtration in AHUs serving office buildings, shopping centres, hotels, and commercial complexes — G4 to F7 grades covering most building regulatory requirements
• Hospitals and Healthcare: Medium and fine grade panel filters in hospital AHUs providing the pre-filtration stage upstream of HEPA terminal filters in operating theatres and isolation rooms
• Pharmaceutical Manufacturing: HVAC panel filters as the primary and secondary filtration stages in classified manufacturing area air handling units — upstream of HEPA terminal units in Grade B–D zones
• Industrial Facilities: Factory and warehouse ventilation pre-filtration — coarse and medium grades protecting AHU heat exchangers and downstream filter stages from heavy industrial airborne dust loading
• Data Centres: Fine grade F7–F9 panels protecting sensitive electronic equipment from airborne particulates in data centre precision cooling units and raised floor CRAC systems
