- Overview
- Recommended Products
Supply Air – Delivering fresh, conditioned air into occupied spaces through ductwork
Exhaust Ventilation – Removing stale air, contaminants, heat, and moisture from enclosed areas
Air Circulation – Maintaining consistent air movement throughout a facility for temperature and air quality uniformity
HVAC Integration – Serving as a key component in central air conditioning systems, air handling units, and other HVAC equipment
The HTFC Series Cabinet Centrifugal Fan (Built-in Motor) represents a thoughtful evolution in ventilation technology. Unlike traditional fans that separate the motor from the airflow path, this unit integrates the motor directly within the cabinet—a design choice that delivers meaningful advantages for modern HVAC installations.
So what makes this fan different? Let us walk through it.
Traditional centrifugal fans often place the motor outside the housing. While this works, it takes up more space, creates additional noise, and complicates installation. The HTFC Cabinet Centrifugal Fan solves these issues with its built-in motor configuration. By housing the motor inside the cabinet, GXF Industrial Fan has created a unit that is more compact, quieter, and easier to install than conventional alternatives.
The fan's core component is a high-efficiency centrifugal impeller—available in both forward-curved and backward-curved configurations depending on the specific model. This impeller is dynamically balanced to ensure smooth, vibration-free operation. The cabinet itself is constructed from high-quality galvanized steel with a durable protective coating, providing excellent corrosion resistance and long service life.
The cabinet features a sound-insulating design with a multi-layer construction: an outer layer of color-coated steel plate for durability and aesthetics, an inner layer of galvanized micro-perforated plate for sound absorption, and a middle layer of ultra-fine glass wool or other insulating materials to further reduce noise. This thoughtful engineering means you get powerful ventilation performance without the disruptive noise typically associated with industrial fans.
The HTFC Series is available in multiple configurations to suit different applications. Type B features the motor built into the cabinet and is designed specifically for ventilation and air supply applications. (For fire protection applications requiring high-temperature operation, Type A with an external motor is also available, capable of running at 280°C for over 60 minutes. But for standard ventilation needs, the built-in motor Type B is your go-to solution.)
The fan supports single-speed, dual-speed, and variable frequency drive (VFD) operation, giving you flexibility to match performance to actual demand. VFD operation is recommended within the 25Hz to 50Hz range for optimal performance and motor protection. With twelve sizes ranging from 9" to 36" in diameter, there is an HTFC configuration for virtually any ventilation requirement.

High Efficiency
– The high-performance centrifugal impeller delivers efficient airflow with reduced energy consumption. The fan's aerodynamic design ensures you move more air with less power—a direct benefit to your operating budget. The broad high-efficiency operating range means you are not paying for wasted energy during off-peak conditions.
Low Noise Operation
– The built-in motor and insulated cabinet design effectively minimize operating noise. The cabinet's multi-layer construction—color-coated steel outer layer, galvanized micro-perforated sound-absorbing inner layer, and ultra-fine glass wool middle layer—significantly reduces noise transmission. Noise levels are kept remarkably low, making this fan suitable for noise-sensitive environments like hotels, hospitals, and office buildings.
Compact Structure
– The integrated motor design saves valuable installation space and is particularly suitable for confined equipment rooms. The compact footprint means you can install it in spaces where traditional fans simply would not fit.
Stable Operation
– The dynamically balanced impeller ensures smooth operation with minimal vibration. Every impeller undergoes rigorous dynamic and static balancing to Grade G5.6 or better, ensuring reliable performance and extended bearing life.
Robust Construction
– The cabinet is manufactured from high-quality galvanized steel with a durable protective coating. The outer color-coated steel plate provides excellent corrosion resistance and a clean, professional appearance. The fan is built to withstand demanding operating conditions.
Easy Maintenance
– Inspection access panels allow convenient routine maintenance and servicing. The removable panels provide easy access to the fan and motor for inspection, cleaning, and servicing without removing the entire unit.
Flexible Installation
– The fan supports both ceiling-mounted and floor-standing configurations, giving you flexibility in system design. The compact structure makes installation straightforward even in tight spaces.
Customization Available
– Customized airflow, pressure, cabinet dimensions, and motor configurations are available. The fan can be equipped with single-speed, dual-speed, or VFD-ready motors. Optional accessories include silencers, filters, and control boxes. Special configurations for corrosive or explosive environments can also be specified.
