Applications
Features & Benefits

Material Strength

This robust and durable unit has a casing manufactured from natural finish Aluzinc, with a louvred air discharge which provides protection against ingress from the elements and is self draining.

Ease of installation

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

Low noise

Single fans have the option of being acoustically lined with Class O acoustic foam so that breakout noise levels are significantly lowered.

Performance

High efficiency low tonal noise 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.

Quality assurance

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

Design Appeal

Ideal for external roof mounting applications where space is a premium.

Full Accessory Range

Speed controllers, fast clamps, silencers, panel filters and flexible connectors.

Warranty

Each SSDR has a 12 month warranty.
Specification

Casing

The unit casing shall be manufactured from 1.2mm thick natural finish Aluzinc. The casing shall be designed so as to minimise vibration and shall incorporate a louvered air discharge guarded against bird ingress. Drain points shall also be provided. Each casing provides an inlet spigot to suit standard circular ducting. 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. Top access panels shall be provided for ease of servicing.

Motors

The Twin range of units may have either an EC or AC external 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 ISO 14694 Grade G6.3 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 9001:2008. They are also tested in accordance with BS848 Part 2 1985 (sound performance) and ISO 5801:2007 (airside performance).
