Air filter

particulatepanelfor air treatment units

Overview
Final-stage minipleat filters for ventilation and cleanroom air handling. Designed to meet classified cleanroom and controlled environment requirements where high-efficiency particulate removal is required (medical, pharmaceutical, chemical, laboratory environments). Manufactured to comply with EN 1822:2009 filtration performance classes.

Construction
Pleated minipleat media with separators (aluminium foil, cotton thread or adhesive) mounted in a rigid frame. Frame options: MDF (wood), aluminium or galvanised steel. Front-facing elastic polyurethane seal ensures airtight installation.

Filtration class

• H10, H11, H12, H13, H14, U15 — according to EN 1822:2009

Standard dimensions

• Frame dimensions (width × height): 305 × 305 mm; 305 × 610 mm; 457 × 457 mm; 610 × 610 mm
• Frame thickness options: 68 mm, 78 mm, 150 mm, 292 mm

Material
Waterproof high-efficiency fibreglass paper composed of micro-fibreglass wrap combined with synthetic fibres, designed for stable performance and moisture resistance.
