Pneumatic Angle De-Scaler Chain Impact Type

This pneumatic angle de-scaler uses a rotating chain impact system to efficiently remove rust, paint, and scale from flat or curved steel surfaces such as ship decks, hulls, and offshore structures. Its angled design allows access to tight corners and edges. The tool operates with minimal vibration, reducing operator fatigue and improving productivity. It is up to ten times faster than traditional needle scalers.

The de-scaler employs disposable chain drums that are replaced entirely when worn—no individual spare parts needed. If a chain breaks, simply remove the opposing chain or rivet to restore balance. The tool requires a compressed air supply with filtration, regulation, and lubrication (FRL) at 6–8 bar (90–115 psi) and consumes 340 L/min. It achieves a surface cleanliness of St3++/SSPC-SP11. Regular lubrication with pneumatic tool oil prevents motor corrosion.

Frequently Asked Questions

What surfaces can this de-scaler be used on?

It is designed for flat and curved steel surfaces such as ship decks, hulls, storage tanks, and structural steel. The angled head helps reach corners and tight areas.

How do I maintain the tool?

Ensure the air supply includes a filter, regulator, and lubricator (FRL). Add pneumatic tool oil regularly to prevent the motor from corroding. Replace the chain drum when worn; no individual parts need replacement.

What if a chain breaks during use?

If a chain breaks, remove the opposing chain or rivet to maintain balance. The tool can continue operating with reduced width.

What air pressure is required?

The tool operates at 6–8 bar (90–115 psi). Lower pressure reduces performance; higher pressure may cause damage.
