Commercial Kitchen Smoke Extraction Project in Riyadh with POPULA XBF Centrifugal Fan
hengshuangda@gmail.com
Commercial kitchen smoke extraction in Riyadh requires careful coordination between the exhaust hood, grease filtration, duct resistance, fan duty, electrical supply, rooftop conditions, and maintenance access. This anonymized engineering case explains how ပေါ်ပူလာ evaluated an XBF multi-wings centrifugal fan for a representative central-kitchen application without treating catalogue limits as guaranteed site performance.
The case is presented as a design reference for overseas buyers and contractors. The project name and operator are not disclosed, and the duty point below is a representative engineering basis rather than a field measurement. Final equipment selection must always be checked against the approved kitchen layout, system resistance calculation, electrical characteristics, local fire requirements, and the manufacturer’s confirmed performance curve.
Commercial Kitchen Smoke Extraction Design Brief
The representative project is a medium-sized catering kitchen serving a hospitality facility in Riyadh, Saudi Arabia. The cooking line includes high-duty appliances beneath a continuous stainless-steel canopy. The proposed exhaust route passes through grease filters, horizontal and vertical duct sections, several elbows, an outdoor discharge section, and the associated transitions and flexible connection.
For preliminary selection, the engineering team used the following design basis:
- provisional exhaust airflow: approximately 12,000 m³/h;
- provisional external static pressure: approximately 900 Pa;
- application: grease-filtered commercial kitchen exhaust;
- installation: service-area or rooftop mechanical zone with duct connection;
- operation: extended daily duty with regular cleaning access;
- environmental concern: high outdoor temperature and dust exposure around the discharge area.
These values are not commissioning results. They establish a provisional point for comparing the system requirement with the manufacturer’s published fan envelope. A final resistance calculation must include the actual hood and filter pressure loss, duct dimensions, fittings, discharge arrangement, fouling allowance, and any air-treatment components.
Why the XBF Centrifugal Fan Was Evaluated
Kitchen extract systems typically require a fan that can move the specified airflow while overcoming resistance created by filters and ductwork. For this reason, a centrifugal configuration was evaluated instead of selecting a general-purpose wall fan based only on air volume.
ထို မီးခိုးထုတ်ယူရန်အတွက် XBF တောင်ပံများစွာပါသော ဗဟိုခွာအားပန်ကာ is intended for smoke-extraction applications where pressure capability and impeller maintenance are important. According to the supplied product sheet, the XBF design applies a modified multi-wing airfoil concept derived from the 11-62 and CF series. The stated design objective is to address the difficulty of cleaning an impeller used in kitchen service.
That feature does not remove the need for grease filtration or scheduled cleaning. The fan should remain downstream of correctly selected and maintained grease filters, while the duct system should include suitable access points. Heavy grease deposition can affect balance, airflow, hygiene, and fire safety regardless of fan type.
Preliminary Selection: XBF 5C C-Type
Based on the supplied catalogue table, the XBF 5C C-type with a 7.5 kW motor was identified as the preliminary candidate. The published data are:
| Parameter | Catalogue value |
|---|---|
| မော်ဒယ် | XBF 5C, C-type |
| Motor power | 7.5 kW |
| Catalogue voltage | 380 V |
| Rotational speed | 1100 r/min |
| Air volume range | 6,469–13,973 m³/h |
| Total pressure range | 1,136–1,140 Pa |
| Static pressure range | 1,073–884 Pa |
| Catalogue noise value | ≤79 dB(A) |
The provisional requirement of about 12,000 m³/h at about 900 Pa falls within the published airflow and static-pressure ranges. This makes the 5C 7.5 kW configuration a reasonable candidate for detailed review, but it is not sufficient by itself to release the fan for manufacture.
Range endpoints in a catalogue do not define every point on a fan curve. Before ordering, the contractor should obtain confirmation of the exact operating point, absorbed power, efficiency, allowable motor load, and stable operating region. The system curve should be plotted against the selected fan curve, with allowance for normal filter loading and realistic installation losses.
Electrical Frequency Must Be Confirmed Before Ordering
The supplied XBF table lists 380 V and a specific rotational speed. The project electrical supply and frequency must be confirmed before purchase. A motor or fan selected from one frequency condition must not be assumed to provide identical speed, airflow, pressure, absorbed power, or noise when connected to a different supply frequency.
For a Riyadh project, the buyer should provide the actual site voltage, phase, frequency, starter or control method, and any local motor requirements. ပေါ်ပူလာ should then confirm the motor configuration and recalculate the duty where necessary. This electrical check is part of fan selection, not an administrative detail.
Installation Details for Reliable Kitchen Exhaust
The preliminary installation concept placed the fan in an accessible mechanical service area connected to the grease-exhaust duct. The following details were included in the engineering review:
- effective grease filtration upstream of the fan;
- straight and unobstructed fan inlet conditions where the layout permits;
- gradual transitions instead of abrupt area changes;
- flexible connections that do not obstruct the airway;
- anti-vibration supports selected for the actual fan and base;
- safe access for impeller, bearing, drive, and duct inspection;
- weather and solar protection appropriate to the final installation position;
- discharge placement that limits recirculation into outdoor-air intakes;
- coordination with the kitchen hood, make-up air, fire-safety, and control systems.
Hot outdoor conditions can influence motor cooling and service life. The mechanical area should not trap discharge air around the fan, and protective enclosures should provide weather protection without restricting ventilation around the motor and drive components.
What Must Be Checked During Commissioning
A rigorous case study should distinguish expected performance from verified performance. Because this article does not present signed site test records, it does not claim a measured temperature reduction, energy saving, noise reduction, or capture efficiency.
For final commissioning, the project team should record:
- airflow by an accepted hood, duct-traverse, or balancing method;
- static pressure at agreed test locations;
- motor voltage, current, frequency, and rotation direction;
- fan and base vibration;
- capture performance at the operating cooking line;
- noise at the specified assessment location;
- make-up air balance and room pressure relationship;
- accessibility of filters, cleanouts, impeller, and service components.
If the measured duty differs from the design requirement, the team should investigate filter condition, damper position, duct leakage, unexpected resistance, inlet disturbance, rotation speed, and motor loading before changing the fan.
Procurement Lessons from the Riyadh Design Case
This commercial kitchen smoke extraction case shows why procurement should begin with a duty point and system description rather than a fan diameter alone. The supplied XBF data allowed the 5C C-type 7.5 kW model to be shortlisted, while the engineering review identified the checks still required before release: exact fan-curve confirmation, electrical compatibility, installation losses, grease management, maintenance access, and local compliance.
For kitchen exhaust projects in the Middle East, South Asia, and Southeast Asia, buyers can send ပေါ်ပူလာ the hood schedule, airflow requirement, duct drawing, estimated static pressure, air temperature, electrical supply, installation location, and destination-market requirements. A complete enquiry gives the manufacturer and contractor a stronger basis for confirming the fan, motor, drive arrangement, and documentation before production.
The result is a more defensible selection process: published data are used as the starting point, engineering assumptions are stated openly, and final performance is verified through approved calculations and commissioning records.
