Summary
See more specification See less specification
The Elta Qube SQU67/500-4-3 is a centrifugal box fan with a 500mm backward curved impeller in a 670mm cube casing, for supply or extract air up to +50°C. It moves up to 6912 m³/h at free air and 3924 m³/h at 500 Pa, the highest pressure in Elta's performance table for this model.
The three phase IP55 TEFC motor (380-415V, 4 pole, 1440 rpm) runs at fixed speed direct on line or variable speed from an inverter. The impeller is EN-AW 5754 aluminium, non-overloading and balanced to G6.3, inside an extruded aluminium frame with 25mm double skinned, mineral wool filled panels that can be moved to give a 90° or straight through airflow. Elta give a 24 month warranty.
- 3 Phase
- AC Motor
- Up to 6912 m³/h
- Speed Controllable
What it is best used for
General supply or extract on a ducted system: a shop sales floor, a college workshop, a changing room block or make-up air for a kitchen. Elta list kitchens, schools, colleges, shops, sports halls, factories, industrial units and warehousing among typical uses. It moves 6912 m³/h free air and about 5868 m³/h against 200 Pa; at that 200 Pa figure it gives roughly 10 air changes an hour in a space of about 590 m³.
It is the wrong fan for hot extract: the Qube SQU is for an airstream up to +50°C, and Elta state it is not suitable for corrosive or explosive atmospheres. For hot or grease laden kitchen canopy extract, choose a Qube SQUHT high temperature box fan, which keeps the motor out of the air stream and is rated to +120°C in the duct.
Why choose this over alternatives
The AC Qube suits a plant room or riser where a simple three phase fan is wanted: it can run fixed speed direct on line, or from Elta's 149-VFD-00-00-0018 inverter when the duty needs trimming. Elta's data show 47.1% overall efficiency at the best efficiency point for this model.
For less air, the Elta SQU67/400-4-3 gives 4140 m³/h free air. For more, the Elta SQU82/500-4-3 gives 7704 m³/h.
Installation notes
- The fan can be mounted at any angle. It arrives set up for 90° airflow; move the panels to make it straight through if your duct runs in line. Make sure it is adequately supported, as it weighs 79 kg.
- Leave access to the panels: they are fixed with multi thread U nuts and lift off for cleaning and maintenance. Elta recommend an inspection at least every 12 months.
- Wire to Elta diagram 152-611 (star connection) with a means of isolation. Connect the motor thermal cut-out into the starter control circuit and use a starter or inverter with overload protection, as fuses and breakers only give short circuit protection.
- Check impeller rotation at first start. Air still comes out of the right side when the impeller turns backwards, but airflow drops and current rises, which harms the motor.
- Elta rate the Qube for ambient temperatures of -20°C to +50°C and up to 95% relative humidity. Site the discharge so it cannot pull flue gases back from any open flued appliance.
You'll also need
- Elta inverter controller 149-VFD-00-00-0018 (3 phase, IP55) for variable speed. Available to order, ask us.
- Elta electric heater battery 018-RH80/50-18-3TP, if you need to temper supply air. Available to order, ask us.

What air temperature is the Elta SQU67/500-4-3 rated for?
Elta rate it for an airstream up to +50°C. For hotter or grease laden air, use the Qube SQUHT high temperature range, rated to +120°C in the duct.
How much air does the SQU67/500-4-3 move?
Up to 6912 m³/h (1.92 m³/s) at free air, 6336 m³/h at 100 Pa, 5868 m³/h at 200 Pa and 3924 m³/h at 500 Pa.
What size are the inlet and outlet?
The 670mm cube casing has a 600mm inlet and a 610mm outlet, per Elta's dimension table. The 500mm in the model code is the impeller diameter, not a duct size, so allow for a transition to your ductwork.
Can the speed be controlled?
Yes, with an inverter. Elta list the 149-VFD-00-00-0018 IP55 inverter for this model. It can also run at fixed full speed direct on line through a starter with overload protection.
Can it be straight through or 90°?
Both. It is supplied set for 90° airflow, and the panels can be moved on site for straight through airflow. The fan can be mounted at any angle.
How noisy is the SQU67/500-4-3?
Elta quote 61 dB(A) at the inlet, 64 dB(A) at the outlet and 52 dB(A) breakout from the case, at 3m in free field. The casing has 25mm acoustic insulation.
