Summary
See more specification See less specification
The Elta Qube SQUHT82/500-4-3 is a high temperature centrifugal box fan with a 500mm backward curved impeller in a 820mm cube casing, rated by Elta for operating temperatures up to +120°C in the duct. It moves up to 8978 m³/h at free air and 6145 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, 1465 rpm) runs at fixed speed direct on line or variable speed from an inverter. The motor sits out of the air stream, so heat, grease and contaminants in the extract do not reach it. 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 12 month warranty.
- 3 Phase
- AC Motor
- Up to 8978 m³/h
- Speed Controllable
What it is best used for
Hot, greasy or contaminated extract inside the building where the fan sits in the duct run, typically above a ceiling or in a plant room: a large commercial or college kitchen, a factory process line or a busy bakery. Elta list kitchens, restaurants, schools, colleges, shops, shower rooms and factories as typical uses. It moves 8978 m³/h free air and 7834 m³/h against 200 Pa, which is enough for a canopy, grease filters and a reasonable duct run.
It is not a smoke extract fan. The +120°C figure is a continuous in-duct running rating, and Elta's datasheet gives no smoke or fire temperature/time rating, so use a certified smoke fan where the design calls for one. It is also not suitable for corrosive or explosive atmospheres. If the air stays below 50°C, the standard Qube SQU range covers the same box sizes without the high temperature build.
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-00-00-0019 inverter when the duty needs trimming. Elta's data show 58.0% overall efficiency at the best efficiency point for this model. If you want built in speed control instead, the Elta SQUHT82/500-EC-3 is the EC equivalent.
For less air, the Elta SQUHT67/450-4-3 gives 6228 m³/h free air. For more, the Elta SQUHT82/560-4-3 gives 11974 m³/h. If the air will stay below 50°C, the Elta SQU82/500-4-3 is the standard temperature version with the same box and impeller size.
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 108 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 warn that the bulkhead and frame can get hot when the fan is handling air at higher temperatures, so keep it clear of anything that could be damaged by heat and guard against contact.
You'll also need
- Elta inverter controller 149-VFD-00-00-0019 (3 phase, IP55) for variable speed. Available to order, ask us.

What temperature can the Elta SQUHT82/500-4-3 handle?
Elta rate the Qube SQUHT for operating temperatures up to +120°C in the duct, with the motor out of the air stream. The datasheet gives no smoke extract or fire rating, so it is for hot kitchen and process air, not smoke control.
How much air does the SQUHT82/500-4-3 move?
Up to 8978 m³/h (2.494 m³/s) at free air, 8370 m³/h at 100 Pa, 7834 m³/h at 200 Pa and 6145 m³/h at 500 Pa.
What size are the inlet and outlet?
The 820mm cube casing has a 730mm inlet and a 740mm 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-00-00-0019 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 SQUHT82/500-4-3?
Elta quote 61 dB(A) at the inlet, 65 dB(A) at the outlet and 53 dB(A) breakout from the case, at 3m in free field. The casing has 25mm acoustic insulation.
