Features & Benefits

Design Appeal

Ideal for roof spaces and / or where space is at a premium.

Low Noise.

Each unit is acoustically lined, therefore the breakout noise levels are low.

Ease Of Installation

All models are designed for direct connection to standard diameter flexible or rigid circular ducting with 50 mm long spigots with EPDM rubber U shaped seals for ease of connection.

Performance

High efficiency backward curved centrifugal impellers are directly driven by an AC or EC external rotor motor, designed to be non overloading and provide high performance characteristics. SQTDCV units are fitted with a non return damper for elimination of short circuiting of air within the casing.

Easy Maintenance

Top and bottom access to the fan and motor is by an easily removable panel for maintenance when required.

Material Strength

A robust, yet lightweight unit with a galvanised sheet steel casing treated internally with a Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining with a fire resistant polymeric coating.

Reliability

Motors and Impellers manufactured by Ziehl-Abegg providing increased reliability.

Mounting

Each unit is supplied with integral mounting brackets.

Motor Protection

All SQTDCV units have integral thermal overload protection which prevents the motor from overheating.

Tested To The Very Latest Standards

SQTDCV units are tested to ISO 5801:2007 (airside performance) and to BS 848 Pt 2:1985 (sound performance) at Elta Fans own test facility, meaning accurate, up to date information on performance and noise data that can be relied upon.

Demand Control

All units supplied with integral controls to provide automated ventilation based on customer requirements complete with remote human interface.

Quality Assurance

All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.

Warranty

Each SQTDCV has a 12 month warranty.

Full Accessory Range Of Accessories

Fast clamps, anti-vibration mounts, silencers, panel filters, and flexible connectors.

Specification

The Quietflow DCV range of in-line twin fans as manufactured by Elta Fans Ltd. 46 Third Avenue, Pensnett Trading Estate, Kingswinford, West Midlands, DY6 7US, UK. Tel: +44 (0) 1384 275800 - If you need more information - Visit demandcontrolventilation.com. Or contact us.

Casing

The robust 1.2mm galvanised mild steel sheet casing, is treated internally with a Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining with a fire resistant polymeric coating. The wrap around folded casing is specially manufactured using integral motor mounting plates to provide additional rigidity for the casings.

Each casing provides a suitably sized circular spigot to suit the duct size required. EPDM (Ethylene Propylene) rubber U shaped seals (being ozone and UV stable) are used to ensure a good seal back to the duct that is to be attached.

A removable lid is provided as a standard feature to facilitate ease of maintenance and cleaning.

Motors

The twin range of units may have either an EC or AC twin rotor motor fitted as standard. The motor contains sealed for life bearings. Thermal Class of motors to THCL 130 or 155 dependent on size.

Manufactured by Ziehl-Abegg providing increased reliability.

All motors are suitable for use in ambient air conditions up to 60°C.

Impellers

High efficiency low tonal noise backward curved centrifugal impeller, dynamically balanced to Grade 6.3 and directly driven by the motor to provide a smooth airflow through the unit.

Quality Management

All units in the Elta range are designed and manufactured to procedures as defined in BS EN ISO 9001:2000.

They are also tested in accordance with BS848 Part 2 1985 (sound performance) and ISO 5801:2007 (airside performance).

* At 2V the average spherical free-field sound pressure levels cannot be accurately measured above the background level in our conventional laboratory facilities. When correctly installed the fan will be inaudible. (less than 20dBA) Tests and preparation of the sound data have been carried out in accordance with BS 848 Part 2:1985 at 50% peak pressure. The In-Duct Sound Power Level Spectra are in dB re-1pW. The overall A-weighted sound pressure level is at a distance of 3m with spherical free-field propagation. It is expressed in dB re-20µPa and is presented for comparative purposes only.

* At 2V the average spherical free-field sound pressure levels cannot be accurately measured above the background level in our conventional laboratory facilities. When correctly installed the fan will be inaudible. (less than 20dBA)Tests and preparation of the sound data have been carried out in accordance with BS 848 Part 2:1985 at 50% peak pressure. The In-Duct Sound Power Level Spectra are in dB re-1pW. The overall A-weighted sound pressure level is at a distance of 3m with spherical free-field propagation. It is expressed in dB re-20µPa and is presented for comparative purposes only.
