A

Balances suction between twin nozzles to prevent stall and maintain pick-up.

Main valve isolating flow to spray bar manifold.

Perforated heat-shield surrounding the auxiliary-engine exhaust pipe. Prevents burns and protects nearby hydraulic hoses from radiant heat.

Adjustable damper located between the suction duct and fan inlet. It allows operators to fine-tune airflow strength for different debris loads and surfaces.

Planned overlap between spray passes to avoid striping.

Additional fuel tank fitted to extend operating time on long sweeping routes. Usually mounted low on the chassis to maintain vehicle balance and easy refuelling access.

Valve equalising airflow between dual suction heads on wide sweepers. Prevents one side losing suction and maintains consistent debris pick-up.

Target litres/m² of bitumen emulsion or hot binder applied by the sprayer bar.

Additional oil cooler fitted to the hydraulic circuit for extreme-temperature work. Prevents system overheating when operating heavy broom or fan loads continuously.

Protective zinc or epoxy coating applied to sweep-gear frames and tanks. Extends service life in areas exposed to road salt and spray.
