Vortice VORT QBK HE SAL 315 4M Cabinet Extractor Fan 45766

45766 is the Vortice VORT QBK HE SAL 315 4M, a high-efficiency self-supporting cabinet fan for ducted extraction in the 315 mm size. A single-phase 230 V, 4-pole motor drives a centrifugal impeller inside a rigid square cabinet, giving 2,159 m3/h at 277.5 Pa with 250 W maximum absorbed power.

A self-supporting cabinet fan for larger commercial extract systems

Cabinet (box) fans such as the QBK HE family are used when an in-line duct fan is too small and a bigger centrifugal unit must sit in a plant room, ceiling void or on the roof deck. The data sheet lists sizes A, B and C of 525 mm for the cabinet envelope, so it can be supported on its own frame and connected to duct on the intake and discharge sides.

Vortice’s booklet describes the product as a high-tech industrial centrifugal extraction fan. The 4M in the model name appears to denote a 4-pole single-phase motor (derived from the code; the data sheet gives 1,400 rpm), and the data sheet also publishes the ErP-style energy data for the unit, including static efficiency of 34.5 % and an SFPint figure.

QBK HE SAL range (Vortice data sheets, values at maximum speed)

Selection and ordering guide

The QBK HE SAL line runs from the 250 EC (1,083 m3/h) to the 630 4T (18,152 m3/h). Here 315 4M is the smallest single-phase mains version, while 315 4T and 315 EC offer a three-phase option (2,195 m3/h) and an EC motor (3,057 m3/h, 526.6 Pa, 350 W). Choose EC where variable airflow is needed; choose the 4M where only a single-phase supply is available.

Because this unit is a straight single-phase motor, check on the data sheet that the drive described (VSD speed control) matches your plan before assuming stepless control; the wiring diagram documents for the product describe the actual connection.

Installation and operation notes

The booklet requires qualified installation, secure support of the 31.6 kg body and connection of the supply to match the data plate. Remember that noise from a cabinet fan can require protection when people work nearby: the English booklet warns that sound-proofing measures or personal protection equipment must be provided where levels are high.

Keep the unit accessible for periodic inspection, check for visible defects regularly and use only original spare parts through the manufacturer, as the booklet instructs.

Applications in Oman and the GCC

Kitchen extraction, car-park and plant-room ventilation, workshop and retail extract where the duty point lies between 2,000 and 3,000 m3/h and a robust self-supporting casing is preferred over a roof fan.

In dusty Gulf locations, keep the extracted air clean through a filter or duct arrangement suited to the contaminants; the data sheet gives IP 55 only for the motor protection, not for the whole cabinet.

Sizing and maintenance notes

Select the fan from its performance curve at the real system pressure, including filters, grilles and duct losses, rather than from the free-air airflow. In hot plant rooms or roof decks, check the motor ambient rating, and inspect the impeller and motor bearings during routine maintenance, especially where dust is present.
