LTG Prefilter

Product catalog summary

Introduction
The LTG Prefilter Series TVM and TVN are designed to filter coarse particles from large air streams. These prefilters are characterized by high air permeability, adaptability to different materials, effective particle separation, and low maintenance requirements. They are rotating, continuously cleaned filter discs suitable for air volumes ranging from 15,000 to 135,000 m3/h.

Applications
The prefilters are ideal for industries with high fiber and particle content in extract air streams, such as textile, nonwovens, woodworking, paper, cellulose, tobacco, and fiberglass industries. The TVM series is preferred for heavy loads, while the TVN series is suitable for smaller, continuous, or intermittent loads.

Advantages

Regenerative filter unit with continuous cleaning to prevent pressure fluctuations.
Space-saving design due to compact disc shape.
Easy access and maintenance with no fiber contamination of drive elements.
Minimized pressure drop due to optimal airflow design.

Technical Specifications
The prefilters are available in different sizes with varying diameters and mesh widths. They operate with a drive motor and belt drive system, and are equipped with thermistor sensor motor protection. The units are shipped disassembled for on-site assembly.

Functionality
The filter disc is mounted within an enclosure, separated by a dividing wall. Continuous cleaning is achieved through suction via a stationary or traversing nozzle, depending on the series. The nozzle does not contact the filter screen during cleaning.

Dimensions and Installation
Detailed dimensions for both TVM and TVN series are provided, including housing and suction connection specifications. The prefilters can be ordered with front and rear housing for modular construction applications.

Additional Information
LTG Aktiengesellschaft offers a range of air technology systems, including comfort air technology, process air technology, filtration technology, humidification technology, and engineering services. They provide customer-specific solutions for product development and process optimization.
