The New range of Slimpak EC single in-line box fans incorporate an energy efficient EC motor and basic commissioning controls to offer an energy efficient basic fan system.

Manufactured from Galvanised sheet the Slimpak (SLP EC) fan units are internally treated with an ‘O’ class rated, BS476 part 6 & 7, acoustic foam, which offers the benefits of high sound absorption and good
thermal insulation properties, in addition to self extinguishing properties and resistance to ignition.

The casing includes an inclined inlet and bellmouth entry which directs the incoming air to the impeller with minimal turbulence. The result is better air management through the unit, less noise, higher efficiency and
an increased performance.

The housing is designed to be as compact as possible for ceiling or plantroom applications with integral mounting points to allow quick and easy installation.

Motor / Impellers
All SLP EC units feature an energy efficient, Class 1, EC/DC external rotor motor and backward curved impeller assembly specifically chosen for performance and non-overloading characteristics. The assembly is dynamically balanced to DIN ISO 1940 Grade 6.3, duct size 500mm rated IP54, all other sizes, IP44 according to BS EN 60529. Ball bearings are greased for life. Insulation is Class ‘B’ (from -25°C to +60°C). All models incorporate internal electronic overload protection and soft start function.

Control
Every SLP EC unit is fitted with a purpose designed integral commissioning controller giving the ability to set the exact duty required at commissioning. Alternatively the integral potentiometer can be bypassed to allow remote speed control via an external 0-10V potentiometer. Low voltage control wiring is kept separate from the mains wiring.

Electrical
Motors are single phase 230V +/- 10% / 50/60Hz / 1ph (size 100-400mm) or 400V +/- 10% / 50/60Hz / 3ph (size 500mm).

Performance/Sound
Extensively tested to BS848 parts 1 & 2. Published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at reference level of 2 x 10-5 Pa. The inlet/outlet sound power level spectra figures are dB with a reference of 10–12 watts.

Quality Assurance
Design and manufacture are in accordance with the standard for quality management systems BS EN ISO 9001:1994.

Accessories
A full range of accessories are available with the Slimpak EC range of fans such as:
• Remote potentiometer speed controller
• Two speed trickle boost controller
• Pre & secondary filter cassettes
