Filter Maintenance Counter

Electronic counter tracking hours since last filter change. Prompts operators when routine service is due to maintain suction efficiency.

Flow-Rate Verification Test

Calibration test comparing measured flow to controller target. Required before major surface-dressing projects to verify accuracy of binder delivery.

Filter-Cartridge Clamp

Quick-release clamp holding cartridge-style filters. Enables safe removal without tools and reduces spill risk.

Flow-Sensor Calibration Routine

Automatic routine run through the controller to verify sensor accuracy. Produces a calibration certificate stored with vehicle records.

Filter-Restriction Indicator

Visual indicator showing filter blockage level. Changes colour when differential pressure exceeds the service threshold.
