SLPT- Slimpak Twin In-Line Centrifugal Fans

Description

Overview

The Slimpak range of streamline twin fan units, which have been designed to allow the unit to be installed as a Run & Standby extract fan or alternatively running both fans simultaneously for optimum performance, offering total flexibility.

Slimpak housings are manufactured from prime quality galvanised sheet steel with circular inlet and outlet spigot connections. To ensure minimum noise levels the units casing is treated with an acoustic lining, Class O rated which offers self extinguishing, zero burn rate, resists ignition and no toxic fume properties.

Each unit incorporates a back draught shutter to prevent air recirculation via the standby fan and to ensure easy access for cleaning and maintenance purposes a full sized access panel is provided to both fans.

Designed and developed to provide one of the most powerful and compact twins in the market, available in three sizes 200, 250 and 315mm dia, with extract performance ranging from 0.116m³/s up to 0.400m³/s (417m³/h to 1,440m³/h), with pressure characteristics of up 550Pa.

Motors

At the heart of the range is a proven 230V/1/50Hz external rotor motor and backward curved impeller assembly. The assembly is dynamically balanced to ISO 1940. Motors are rated to IP44 according to BS EN 60529. Ball bearings are greased for life and allow the fan to run at any angle. Insulation is Class 'B' (from -15°C to +40°C).

All Acoustic fans are suitable for speed control, an Auto Transformer is recommended to ensure minimum noise levels during speed control so eliminating any possibility of motor harmonic noise.

Performance and Sound

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 10-5 Pa (20 micro-Pascal). The inlet, outlet and breakout sound power level spectra figures are dB with a reference of 10-12 Watts (1 pico-watt).

Quality Assurance

Design and manufacture shall be in accordance with BS EN ISO 9001:1994.
