AC Infinity Noise Reduction Clamp, Duct Coupler with Stainless Steel Clamps, 100 mm

Product detailed description

A coupler that reduces vibrations directly at the duct connection

AC Infinity Noise Reduction Clamp RCA4 is a rubber coupler for connecting two ends of ventilation ducting with a diameter of 4" (10.2 cm). It fits onto the ports of fans, carbon filters, grilles or dampers in smaller 100 mm systems and creates an airtight connection - the flexible nitrile rubber also absorbs sound waves and vibrations transmitted from the fan into the airflow in the ducting.

Material and mounting

The coupler body is made of NBR grade 65A nitrile rubber in a matt black colour - flexible, durable and easy to stretch over ports and ducts. Mounting is provided by two adjustable stainless steel hose clamps with a worm-drive lock, whose heads can be tightened with either a Phillips or flat-head screwdriver.

Pair with a 100 mm system

Use the coupler when connecting ducting, carbon filters, inline fans, grilles or dampers with a diameter of 4" in grow tents, grow rooms and standard HVAC systems. Combine it with other components of the same diameter:

• AC Infinity CLOUDLINE A4 - quiet 100 mm inline fan.
• DCF4 Carbon Filter - odour filter of the same diameter.
• 100 mm Flexible Four-Layer Ducting - connects the filter to the fan.
• DSA4 Silencer - addresses a different issue: it reduces airflow noise along the ducting route, not vibrations at the connection.
• DCA4-2 Replacement Stainless Steel Clamps - separate clamps without a rubber coupler, for mounting other connections.

Frequently asked questions

Is it the same as a silencer?
No. RCA4 is a coupler that seals and reduces vibrations at one specific duct connection. The DSA4 silencer is a separate part inserted into the ducting route that reduces the noise of moving air.

Are the clamps included?
Yes, the package contains two adjustable stainless steel hose clamps with a worm-drive lock.

What duct diameter is the RCA4 suitable for?
For components with a diameter of 4" (10.2 cm) - fans, filters, grilles and dampers.
