Available in 4 standard sizes from 250mm to 500mm.
Air volume flow rates up to 3.80 m³/s.
Static pressures up to 600 Pa.
Suitable for temperatures up to +200°C.
Can be mounted internally or externally.

Casing: Constructed from sheet steel, the casing is robust and long-lasting. It is hot dip galvanized to BS EN ISO 1461:1999 standards.

Impeller: Features adjustable pitch aerofoil impellers made from high-quality pressure die-cast aluminum, dynamically balanced to ISO 14694 Grade G6.3.

Motors: Foot-mounted, totally enclosed metric type motors with IP55 protection, sealed bearings, and Class H insulation to EN 60034-5.

Quality Management: Designed and manufactured under BS EN ISO 9001:2008 procedures. Tested to ISO 5801:2007 for airside performance and BS 848 Part 2:1985 for sound performance.

Applications: Suitable for kitchen extract, spray booths, hot gas situations, corrosive atmospheres, boiler houses, and heavy industrial environments.

Performance Data: Detailed performance, SFP, and electrical data are provided for both single-phase and three-phase models, including airflow rates, static pressures, and sound data.
