This product range is now obsolete and no longer available from Vent-Axia. The information here is provided for reference only.

The ACCESS range of rectangular backward curved in-line fans have been specifically designed with the latest COSHH (Control of Substances Hazardous to Health) regulations in mind.

These regulations make it a requirement for employers to provide effective methods to control exposure to certain hazardous materials and substances in the work place utilising general or local exhaust ventilation systems. The regulations also require that the system installed be inspected and maintained on a regular and documented basis.

ACCESS has been developed for commercial and industrial applications with the emphasis on fast installation, reliable performance and access for inspection. It features a new generation of backward curved fans specially selected for their performance and non overloading characteristics.

This range of rectangular fans are available with matched accessories for complete ventilation systems in a variety of ducted applications. The innovative and compact design of the galvanised steel casing, backward curved impeller and motor unit ensures that the Access model occupies no more space than ordinary forward curved units.

An access panel on all models comes complete with the motor and impeller assembly mounted on it making maintenance a swift and simple procedure.

Motors / Impellers

The range is powered by a proven external rotor motor and impeller assembly dynamically balanced for quiet, vibration free performance. Motors are rated IP44 according to BS EN 60529. Bearings are greased for life and are designed to run at any angle. Motor insulation is Class 'B'. 100 to 315 Ø operating temperatures 50°C; 355 to 710 dia 40°C.

Manufacture of the motor impellers, casings and assembly are all controlled to BS EN ISO 9001 standards. The motor/impeller assemblies are dynamically balanced to VDI 2060.

Electrical

Single phase 220-240V 50 Hz. Capacitor start and run. The capacitors are located in the terminal box where possible. Three phase 380-415V 50 Hz. The terminal box on models 355 to 710 are protected to IP54 according to BS EN 60529. All motors are fitted with Standard Thermal Overload Protection (S.T.O.P.), which should be wired into all controller circuits and into starter contactors. Models are available with 2, 4, 6 and 8 pole motors.

Performance
Tested to BS 848 Parts 1 & 2. Published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at a reference level of 2 x 10–5Pa (20 micro-Pascals). The inlet and outlet sound power level spectra figures are dB with a reference of 10–12 Watts (1 pico-watt).

Accessories
Rectangular flexible connections, attenuators and bag filter cassettes.
