Benefits of Direct Drive Fans
Energy Savings
Eliminating drive losses from the belt and pulley can improve mechanical efficiency by up to 5%.
Lower Maintenance
A direct drive fan requires minimal maintenance. The routine maintenance of lubrication and belt tensioning is eliminated.
Low Noise Level
Much of the noise in ventilation units is created by the moving belts. Without a belt, the sound level is frequently lowered by 3-9 dBA. As a result, sound attenuation components can be smaller, and in some cases can be eliminated. Smaller sound attenuators decrease the degree of static pressure drops. Savings are in both initial installation cost and in improved system efficiency.
Motor Longevity
By nature of design, Direct Drive Fans must be controlled by a Variable Frequency Drive (VFD). The controller acts as a soft start, greatly reducing the stress on the motor, and in turn minimizes the risk of motor failure.
Many options exist to minimise energy consumption by replacing older less efficient fans and motors.
BRICs direct drive fans are designed to provide optimum value to the designer, installer, and end user. They come in two categories: Direct Drive Centrifugal Fans (DS fans, DD fans and DDEM fans) and Direct Drive Constant Volume Fans with EC Motors (DDEC fans). All fans feature a robust construction and their constant quality make them equally suitable for installation in supply and exhaust air systems, and in original equipment where it contributes to the equipment manufacturer’s reputation for the consistent performance and reliability of their product.
Direct Drive Centrifugal Fans
Robustly constructed direct driven centrifugal fans with heavy gauge galvanised steel casings, and motors in or out of the airstream.
DS (Single Inlet) and DD (Double inlet) range
- Volume flows from 100 to 7000m³/hr
- Forward curved dynamically balanced impellers.• Anti-vibration motor suspension for vibration free, quiet operation.
- Speed controllable
- Equally suitable for installation in supply and exhaust systems,and in original universal equipment
- Suitable for handling air at temperatures up to 50ºC
- IP44 enclosure motors
DDEM Single inlet fans with motors fitted externally out of airstream
- Volume flows from 1000 to 10000m³/h
- Forward curved(DDE/EM) and backward curved DDEB/EM dynamically balanced impellers
- Cube constructed casing easily connected to flanged ducting
- Motor and impeller easily removed for cleaning
Direct Drive Constant Volume Fans with EC Motors
A new generation of small DDEC fans with high efficiency EC (electrically commutated) motors, speed regulated to maintain constant air volume flow with varying pressure loss.
- Air volume flows from 350 to 4500m³/h
- Double inlet
- Heavy gauge galvanised steel casings
- Forward curved dynamically balanced impellers
