Delta Delta-F Sound Moderators

Roedale Delta-F Sound Moderators are a no licence required ( 18years+) sound moderator designed for use on Airguns and are manufactured from the highest grade high strength aluminium alloy. Each part is manufactured from the highest grade high strength aluminium alloy used in the aerospace and defence industries. Parts are CNC machined from solid billets. The surfaces are hardened and coated with a hardcoat-anodizing finish to Mil-Spec type III matt black. This coating lends numerous functional qualities to aluminium components.

Wear-resistance and hardness: The high wear-resistance is based on the hardness and the morphology of the aluminium oxide coating. The attainable hardness of the layer lies between 400 and 500 HV0,025.
Heat conductivity: The heat conductivity amounts to from around 1/10 to 1/30 of the heat conductivity of the base material.
Temperature resistance: Hardcoat layers withstand brief temperature peaks to 2,200 K.
Impact Resistance: The impact resistance complies with ISO 2376 and amounts to 50 µ m: 1213V.
The aim of this coating procedure is functionality and not beauty. Minimum colour differences on the surface may occur between batches.
The Delta-F achieves excellent peak noise reduction on Airguns

Roedale Delta-F Moderators offer the following advantages:

• Weight: from 140 g
• Diameter: 39.7mm (1.56“)
• Length: 95mm (3.74“) long
