modular cleanroom solutions: fan filter units

 

 

 

 

 
Our Fan Filter Units have backward curved impeller run by a high efficient and variable speed motor inside, which is available for a full range of voltage options.
This compact unit is located in the ceiling grid and does not require very much space. In connection with either HEPA or ULPA filters it provides the solution for your air cleanliness needs.

SH-HNT's Fan Filter Units incorporate a highly efficient backward curved plenum fan with a high-efficiency brushless variable speed motor.

These FFUs are available in standard 2'x4' and 4'x4' (600x1200mm and 1200x1200mm) nominal sizes and also custom sizes. 
Our FFUs reduce operating costs and provide an unprecedented amount of monitoring and control features for seamless fab operation.   
Easy unit control and maintenance !
The benefits are

- Reduction of production and   installation cost.
- Low noise levels.
- Easy unit control and maintenance
- 100% speed control.
- Full monitoring.
- Simple installation and maintenance.
- The FFU's can either be fitted from the   Cleanroom side (room-side-replacable)   or from above the ceiling level.
- Flexible air filter options.

Notes

1.The results tested can vary due to different meteorological conditions, which might cause different air density.

2. The air flow measured on site may not be the same as shown above. There reasons for this can be:
Air density : The tested results apply when the fan is in operating condition. In a typical Cleannromt, the air is normally less dense which increases the flow at any given frequency.

Static pressure : At any frequency, the static pressure must be known. Static pressure measured on site is normally carried out by tube inserted into the fan housing. Unfortunately, it is normally not possible to tell if the air inside is flowing across the tube or into the tube’s end. Thus, some of the measured static pressure may be due to velocity pressure. The result is a measure of more static than actually exists. The curves then will predict less flow.

Flow Measuring device : Measuring air flow (CMH) on site can be inaccurate. Calibration and measuring procedure must be strictly followed. Pressure based meters such as flow grids are sensitive to eddies at the filter face and will normally read higher flow than the actual average flow. Collection meters such as hoods can add additional static pressure. They usually have a correction procedure to compensate for this.
