Air Purifiers for Workshops, Service Areas and Technical Indoor Environments

Function of Air Purifiers

Air purifiers do not filter engine intake air, but instead clean the surrounding air within the working environment. They are used where airborne contamination must be reduced independently from the machine’s filtration system.

Unlike complete air filter systems and air filter elements, air purifiers operate on a room-based level rather than within the engine air intake path.

System Design and Filtration Stages

Air purifiers in this category typically use multi-stage filtration systems. These include pre-filtration stages for coarse particles and high-efficiency main filter stages for fine particle removal.

• Pre-filters: protect and extend the life of the main filter stage
• Main filters: fine and particulate filtration depending on system design
• Replacement filter sets: matched to specific air purifier systems

Filter configuration depends on device type, operating environment and required air purification performance.

Typical Applications

• workshops and service areas
• technical workspaces
• enclosed indoor environments with high dust exposure
• indoor areas requiring independent air purification outside machine filtration systems

Air purifiers are primarily used where contaminated indoor air must be reduced independently of machine operation.

Devices and Replacement Filters

This category includes both complete air purifier units and matching replacement filter sets or filter elements. In practice, correct matching between device and filter is essential, as filter media, geometry and service kits are system-specific.

Selection is based on device designation, reference number and required filter configuration.

Difference to Cabin and Machine Filters

Unlike cabin filters, air purifiers are not integrated into the machine’s HVAC or ventilation system. They operate as standalone units for ambient air cleaning.

They are also functionally distinct from intake system components such as pre-cleaners (cyclones), rain caps or air intake components, which operate directly within the engine air intake system.

Position within the Filter System

Air purifiers are part of the construction machinery filter category, but function independently from engine air filtration. Their role is to improve air quality in technical working environments rather than to protect engine components.

Selection and Identification

Selection is based on device designation, reference number, filter stage and replacement filter compatibility. Matching the correct filter set to the device is essential.

Visually similar filter packs or incorrect system allocation are common causes of ordering errors.

Check Before Ordering

• device designation
• reference number
• filter stage / filter type
• replacement filter or complete unit
• intended operating environment
