The inline

WET FAN BOX SCRUBBER

It’s ALL about clean air

LOW dust counts

The in line design with compact size, low power and water consumption, lower weight, easy maintenance and great performance, gives the world’s most efficient axial fan in line wet scrubber. The in line wet fan box scrubber uses well proven and long established design principles with modern state-of-the-art design and construction technology to give a highly efficient compact wet scrubber.

The units were designed specifically for use on coal dust and have been highly successful in the coal mining industry. The water cooled motor is built to Class II Div.I, and operates in a cool air stream and a continuous water spray. The motor has a long history of reliability,

The units are available in a range of sizes from 4m³/sec to 17m³/sec. Each unit is supplied with pressure / flow monitor system to ensure that there is adequate water flow thourgh the motor and spray nozzles.

1. WET FAN BOX SCRUBBER

The wet fan box scrubber units were developed using the CSIR Aerotech Division’s computer simulation programs to design a high efficiency, low inertia axial fan driven by water cooled electric motor. The scrubber box has a highly efficient mist eliminator and screen. The unit is compact, lightweight, low power and water consumption to give high performance and efficiency. The design allows for easy installation, maintenance and a fast change out of the fan assembly should this become

damaged.

2. SPRAY FAN SYSTEM Pioneered the development of the spray fan system for continuous miners in South Africa. They have been installed on just about every continuous miner used in the country and the basic design is still a mainstay in the industry. We have now developed a reverse flow back cleaning system to enhance performance, reduce maintance and increase efficiency. Both systems continue to enjoy widespread popularity and ensure good dust suppression and pick lubrication, as well as assisting with air movement across the face.

3. AIR MOVERS The air movers have been developed to provide optimum air movement with minimum water consumption. Strategically placed on the CM, they can develop significant air movement past the operator and into the scrubber unit to ensure good dust capture. When they are used in conjunction with the wet fan box scrubber unit, very low dust levels in the operating area can be achieved.

4. BOOSTER PUMPS Our ranges of booster pumps are designed to provide the optimum water flow and pressure required by the dust suppression system. The pumps are of rugged design, enabling them to operate under the most severe conditions to give long life with minimum maintenance. They are supported by a 24 hour service exchange scheme to reduce stockholding and turnaround time.

5. WATER FILTERS Our range of water filters have been developed over nearly 20 years of operating experience in the coal mines. They are extremely rugged, highly efficient and required minimum maintance, to ensure good protection to pumps, nozzles and other components in the dust suppression system fitted to continuous miners. The range includes high and low pressure manual back flush units, a high pressure automatic back flush filter and the all-new semi-automatic flush filter and valve.

6. 24 HOUR SERVICE SUPPORT We are committed to a 24 hour, seven days a week support with service exchange units for pumps and fans together with fast repair turnaround times in its own workshop for all the equipment in its programme. When you fit RDP equipment to your CM you not only get good dust suppression equipment but also 100% commitment by the company for round-the-clock filed support. Our customer support engineers and service technicians are available at all times to assist you in the supply, operation and maintenance of all RDP’s dust suppression equipment.

The wet fan box scrubber units have been proven in independent tests to be highly effective and reliable. The wet fan scrubber unit is the main component in the integrated dust suppression system which is recommended to achieve optimum dust suppression in mechanised underground coal mining. The integrated dust suppression system comprises of the wet fan scrubber unit operating in combination with air movers and a spray fan. These reliable, tried-and-tested dust suppression system are configured to operate in a complementary way to ensure that dust counts do not exceed 5mg/m³.
