The QUBe SQU is a multi-discharge, double skinned fan unit incorporating the high performance backward curved Ziehl-Abegg RH-C impeller designed specifically for operation without a scroll. Supplied for straight through airflow with the outlet panel positioned directly opposite the inlet panel, but the outlet panel can be easily exchanged on-site to provide 90° airflow if required.
- 4 physical sizes with 5 models from 315mm to 710mm.
- Air volume flow rates of up to 3.9 m3/s.
- Static pressures of up to 928 Pa.
- Suitable for operating temperatures up to +50°C.
- Interchangeable double skinned panels.
- Inverter speed controllable via 1Ph and 3Ph supply.

Features & Benefits
Self supporting corrosion-resistant extruded Aluminium section, assembled with shock resistant fibreglass reinforced Polyamide PA6 corners ideally suited for general ventilation applications.
Three phase multi-voltage IP55 TEFC motor, wound for either (Delta) 230V/3Ph/50Hz or (Star) 400V/3Ph/50Hz connection, which is mounted using a unique low loss X-frame internal mounting arrangement, improving performance, and reducing noise generation, suitable for speed control with the Eltadrive VSD range of frequency inverter controls.
Motors are pre-wired to an IP55 terminal box mounted on the side, for easy customer connection.
Quality Impeller Design
High efficiency backward curved impellers with non-overloading power characteristics.
Straight through airflow as supplied. Discharge position can be altered on site.
All QUBe units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2: 1985 (sound performance).
Ease of installation
All models are designed for direct connection to standard diameter flexible or rigid circular ducting with 50mm long spigots for ease of connection. Each spigot has an integral E PDM (Ethylene Propylene), UV + Ozone stable and resistant rubber seal which has a U shaped profile.
Full accessory range
Flexible connectors, attenuators, Eltadrive VSD frequency inverter controls, Eltadrive VSD frequency inverters (1Ph and 3Ph supply).

Constructed from self supporting corrosion-resistant extruded aluminium section. Straight through airflow as supplied. Discharge position can be altered on site.
The inlet and outlet panels incorporate circular spigots with integral U-shaped ozone and UV stable EPDM rubber seals to prevent duct leakage.
Assembled with shock resistant fibreglass reinforced Polyamide PA6 corners, and 25mm thick double skinned removable panels, manufactured from pre-galvanised steel, in-filled with a non flammable mineral wool, 60kg/m³, thereby minimising breakout noise.
A high efficiency backward curved welded steel impeller with a non-overloading power characteristic, finished with a powder coating to RAL 5002 for greater surface protection, and dynamically balanced to G2.5 / G6.3 according to ISO1940 part 1.
Three phase multi-voltage IP55 TEFC Foot / Flange mounted IEC frame motors, wound for either (Delta) 230V/3Ph/50Hz or (Star) at 400V/3Ph/50Hz connection, suitable for speed control when used with the Eltadrive VSD range of frequency inverter controls. Motors are pre-wired to an IP55 terminal box mounted on the side, for easy customer connection.
Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001:2008. All SQU units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
