Wohler Helicopter Nozzle 7556 Compressed Air Cleaning, Backward Rotating

The Wohler Helicopter Nozzle 7556 is a pneumatic cleaning nozzle for compressed-air cleaning in small ducts. It combines brush-compatible airflow with blast-pipe effect to loosen persistent contamination during duct maintenance. It is suited to compact ventilation cleaning workflows where controlled movement and concentrated cleaning action are required.

- Reverse nozzle rotation directs cleaning force to drive the nozzle forward through the duct.
- Compressed air works together with brushes to loosen and carry contamination away from the cleaning path.
- Helicopter-style nozzle motion helps maintain cleaning action along the duct interior during movement.
- Blast-pipe effect concentrates airflow where buildup is persistent in smaller duct runs.

- Designed for compressed-air cleaning workflows.
- Built for use in small ducts where persistent contamination requires concentrated airflow.
- Intended to operate in brush-assisted cleaning setups.
- Compatible within Wohler compressed-air cleaning system configurations, including the Standard Set 7560, Professional Set 7570, and DH 420 Pneumatic Viper applications.

- Small ventilation duct cleaning.
- Compact duct maintenance where debris buildup is difficult to remove with passive airflow alone.
- Dryer vent and similar small-duct cleaning workflows supported by Wohler compressed-air cleaning systems.
