Summary
See more specification See less specification
The Elta Qube SQUHT67/450-EC-1 is a high temperature centrifugal box fan with a 450mm backward curved impeller in a 670mm cube casing, rated by Elta for operating temperatures up to +120°C in the duct. It moves up to 7027 m³/h at free air on full (10V) speed and 4327 m³/h at 500 Pa, the highest pressure in Elta's performance table for this model.
The single phase IE6 EC motor (220-277V 50/60Hz) is IP55, has a built in variable speed drive with protection against overload, over temperature and locked rotor, and takes a 2-10V, PWM or potentiometer speed signal. 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.

- 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 7027 m³/h free air and 5803 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
An EC Qube needs no separate inverter: the drive is built into the motor, so speed is set from a simple potentiometer or a 2-10V BMS signal, and turning it down saves energy. At 7.5V this model gives 5076 m³/h free air and at 5V 2995 m³/h, so one fan can be commissioned to the exact duty. The Elta SQUHT67/450-4-3 is the AC version in the same box size, which runs at fixed speed or from a separate inverter.
For less air, the Elta SQUHT50/350-EC-1 gives 3510 m³/h free air. For more, the Elta SQUHT82/560-EC-1 gives 10858 m³/h. If the air will stay below 50°C, the Elta SQU67/450-EC-1 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 70 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 152-733 or 152-736 (see product label) with a means of isolation. For external speed control from the 149-POT-10-MI or a BMS, remove the jumper on the control board. The label shows which of the two diagrams applies, and the maximum control cable lengths differ between them, so check before running long control cables.
- Disconnect the fan before any insulation resistance testing, as the test can damage the EC electronics and that is not covered by warranty. The motor has an auto reset thermal contact, so isolate the supply before working on it because it can restart once cool.
- 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. The EC motor may also slow itself down automatically under excessive load or temperature.
You'll also need
- Elta EC Electronic Controller 149-POT-10-MI for manual speed control (Elta's listed controller for this fan).

What temperature can the Elta SQUHT67/450-EC-1 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 SQUHT67/450-EC-1 move?
Up to 7027 m³/h (1.952 m³/s) at free air on 10V, 6487 m³/h at 100 Pa, 5803 m³/h at 200 Pa and 4327 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 450mm in the model code is the impeller diameter, not a duct size, so allow for a transition to your ductwork.
How do I control the speed?
The EC motor has a built in drive. Use the Elta 149-POT-10-MI controller, or a 2-10V or PWM signal from a BMS, after removing the jumper on the control board.
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 SQUHT67/450-EC-1?
Elta quote 60 dB(A) at the inlet, 63 dB(A) at the outlet and 50 dB(A) breakout from the case, at 3m in free field on full speed. Turning the speed down reduces this.
