Ceiling Filters for Paint Spray Booths

Ceiling filters are depth-loading filter media used in the final stage of supply-air filtration in paint spray booths. Their synthetic-fibre structure has progressively increasing density and captures dust before the air reaches the spraying area, helping protect freshly painted surfaces.

The filter medium is made from polyester fibre and includes a support mesh on the clean-air side. This stabilises the medium and limits fibre migration in the direction of airflow.

Construction and operating conditions

• basis weight: 600 g/m²;
• thickness: 20 mm;
• maximum operating temperature: 100 °C;
• relative water resistance: 100%.

The required filter area and replacement interval should be determined from the airflow rate, permitted pressure drop and cleanliness level required inside the booth. Actual performance depends on air velocity, filter loading and the operating parameters of the installation.
