Rotary Pre Filter (RPF)

The Luwa Rotary Pre Filter (RPF) is an essential component in the textile industry's air filtration systems. Designed as a preliminary filtration stage, the RPF efficiently handles larger air streams heavily charged with waste from production machines. This unit is part of the proven compact centralized air handling system, TexPac, and is optimally combinable with several function modules. The RPF stands out thanks to its simple, space-saving design and reliable functionality.

Applications of Luwa Rotary Pre Filter

• Separation of Textile Waste and Fibres: Efficiently removes waste and fibres from air streams.
• Pre-Filtration in Multi-Stage Systems: Serves as an effective pre-filter in multi-stage filtration systems.
• Room Return Air Filtration: Can be used as a single-stage air filtration system for room return air in production areas, such as those handling wool or man-made fibres with low dust generation.

Key Features of Luwa Rotary Pre Filter

• Sturdy Construction: The pre-filter part, featuring a rotating filter disc and stationary suction nozzle, is integrated into a robust sheet steel housing. Access is provided through a lockable service door with a large inspection window.
• Continuous Cleaning: Cleaning is continuously performed with a small air volume by the suction nozzle. Coarse particles and fibres are either conveyed to the disposal station or recycled.
• Overload Protection: A pressure-controlled device protects the filter screen against overloading.
• Customizable Parameters: The pre-filter can be optimally adapted to varying operational conditions through selectable parameters such as mesh size of the filter screen and rotation speed.
• Space-Saving Design: Occupies minimal space, making it ideal for various installation environments.
• High Negative Pressure Tolerance: Operates efficiently under high negative pressures, up to approximately 3000 pascals.

Advantages of Luwa Rotary Pre Filter

• No Need for a Filter Chamber: Eliminates the need for customers to provide a filter chamber.
• Compact Design: Requires minimal space and is easy to install.
• Modular: Can be individually adjusted to specific circumstances.
• Easy Monitoring and Maintenance: Simple to monitor and access for control and maintenance.
• Reliable Operation: Ensures continuous suction for reliable performance.

Available Options

• Variety of Filter Screens: Available in several types and mesh sizes, including steel.
• Adjustable Rotation Speed: The rotation speed of the filter disc can be adjusted during operation to meet varying requirements.
• Connection Box: Available for easy piping connections.

The First Step to Optimal Filtration

The Luwa RPF acts as the initial, vital component in your two-stage filter system, ensuring the efficiency and longevity of your overall air filtration setup. Its proven design requires minimal space and offers a very low pressure drop. The continuous extraction of the disc-shaped filter eliminates pressure fluctuations within the air cleaning process, making it a reliable and efficient choice for your textile production needs.
