Description

Product Overview

The Sy-Klone RPUR004 Recirculating Unit is a powered 24-volt air-filtration module designed to pull air from inside the cab, filter it through a HEPA-rated element, and return cleaner air to the operator space. Because it continuously cleans the recirculated cabin air, it helps reduce operator exposure to fine particulate found in construction, mining, forestry, agriculture, and waste-handling environments.

This recirculation module supports HVAC efficiency by reducing dust load inside the cab and lowering the burden on fresh-air systems. The integrated HEPA filter captures extremely fine particulate, and the sealed housing helps prevent bypass air. Its 24V motor offers consistent airflow and is compatible with modern heavy-equipment electrical systems.

The RPUR004 installs easily and serves as a complete replacement for recirculating units in RESPA-equipped cabins.

Applications & Fitment

The RPUR004 is used on heavy-duty equipment requiring continuous cabin air recirculation and fine particulate removal, including:

• Construction machinery

• Mining haul trucks and loaders

• Forestry processors

• Agricultural tractors and sprayers

• Industrial off-road vehicles

• Waste-handling and landfill equipment

It installs in RESPA-equipped cabs where recirculated air must be filtered through a HEPA element.

Maintenance

Inspect the unit during routine cab service. Replace the HEPA filter when airflow begins to drop or when dust loading becomes visible. Ensure the motor operates smoothly and the housing seals remain intact. Clean dust from the intake and outlet areas to maintain performance.
