Product Overview
The Quiet Pack in-line acoustic fans shall be as supplied from Roof Units, designed around a high performance centrifugal impeller, offering a highly efficient, quiet and compact in-line acoustic fan.
The Quiet Pack fan range is manufactured from prime quality galvanised sheet steel, ensuring a robust in-line fan for those tough site conditions.
Quiet Pack casings are suitable for internal mounting only and internally treated with an ‘O’ class rated acoustic foam, which offers the benefits of excellent low level duct bound and breakout sound levels, in addition self extinguishing properties, zero burn rate, resistant to ignition, and no toxic fumes.
Quiet Pack fans are suitable for circular ducting ranging in sizes 100, 125, 150, 160, 200, 250, 315, 200 and 500mm, with air volumes from 0.016m3/s to 1.8m3/s and pressure development of up to 500Pa.
The casing are specially designed to allow the unit to be mounted via drop rods or anti vibration mounts, ensuring a quick and easy solution to installation of the Quiet Pack in-line acoustic fans. All manufacturing progressed of the Quiet Pack fan units are computer designed and controlled to BS EN ISO 9001 Standards.
Impellors
The motor and backward curved impeller shall be factory matched, statically and dynamically balanced on precision machines, to DIN ISO 1940 Grade 6.3, to give quiet, vibration free running.
Motors
Motor insulation Class B, suitable for operating temperatures from -15°C to +40°C and atmospheres up to 95% RH. All sizes are ideally suitable for speed control by electronic or voltage reduction. Vent-Axia would recommend that a voltage reduction Auto Transformer speed controller is used with all Quiet Pack units to ensure minimum noise levels during speed control and to eliminate any possibility of harmonic noise levels which may occur when using electronic speed controllers at lower speeds.
Performance
The fan performance, shall be in accordance with tests to BS848 Part 1 1980, with the fan sound levels, measured in a reverberant chamber in accordance with BS848 Part 2 1985.
Quality Assurance
Design and manufacture shall be in accordance with the standard for quality management systems BS EN ISO 9001:1994.
