Spray Booth Ceiling Filter FAQ: Specifications, Ordering and Support Questions

Buyers, distributors and paint-shop engineers often have the same set of questions before ordering a spray booth ceiling filter. The F5 Ceiling Filter / Roof Filter for spray booths is offered by Hebei Fangyu Trading Co., Ltd.

What material is the F5 spray booth ceiling filter made from?

The filter is constructed from 100% polyester fibers. The medium-effect filter cotton incorporates a fine fiber layer designed for fracture resistance, with fiber density increasing gradually along the air-flow direction. The main body uses an anti-volatile solvent compound and contains no organosilicon. The outer top layer is covered with a polyester grid that helps distribute airflow evenly across the ceiling surface.

What filtration class does the ceiling filter carry, and what efficiency does it achieve?

The filter is rated F5 / M5 under EN 779 and EU5 under Eurovent. In technical testing both the 20 mm and 25 mm variants achieve a filtration efficiency of 98%, which qualifies them as medium-efficiency filters suitable for automobile spray and paint workshop environments.

What thicknesses are available, and how do the technical performance figures compare?

Two standard thicknesses are offered:

The 25 mm variant offers a higher dust-holding capacity (500 g/m² versus 438 g/m²), which can extend service intervals in high-paint-load environments.

What is the weight of the spray booth filter media?

The filter media is available in two weights: 550 g/m² and 600 g/m², reflecting the two thickness options.

What are the temperature and humidity limits for this spray booth ceiling filter?

The maximum operating temperature is 120 °C. The filter is rated for 100% relative humidity, making it suitable for water-based paint systems and high-humidity spray environments.

Where is this ceiling filter typically used?

The product is primarily used in automobile spray booths, paint workshops and assembly workshop ceilings. It functions as intake ceiling cotton, guiding clean, evenly distributed airflow downward across the work area to maintain a dust-free spray environment.

What structural features help the filter resist fiber breakage and shedding?

The fiber layer density increases progressively along the direction of airflow, maximizing tensile strength while keeping pressure resistance low. After spraying or dipping, the high-temperature powder fully permeates the medium so fibers do not break or shed. This design also prevents dust particles from penetrating through the media. The anti-volatile solvent compound used in the main body does not contain organosilicon, reducing contamination risk in sensitive coating environments.
