AC Infinity – 100mm Stainless Steel Noise-Reducing Clamp / Collar

AC Infinity AC-RCA4 – 100 mm anti-vibration connector for ventilation

The AC Infinity AC-RCA4 is a 100 mm / 4" rubber ventilation connector designed to provide a durable and airtight connection between ventilation system components. Its flexible design helps reduce the transmission of vibrations and noise generated by the fan, while also sealing the connection point.

The AC-RCA4 is particularly well-suited for connecting a 100 mm duct fan to a carbon filter, but it can also be used with ducts, pipes, and other compatible ventilation components. It’s a practical solution for grow boxes, grow rooms, and HVAC systems.

Less vibration and noise in the ventilation system

A running fan generates vibrations that, with a rigid installation, can be transmitted to the filter, pipes, and other parts of the system. The AC-RCA4’s flexible body creates an insulating layer between the connected devices, helping to dampen vibrations and reduce the resulting noise.

This connector can be particularly useful in small grow boxes, where the fan and filter are located close together, and vibrations easily transfer to the tent structure and ventilation ducts.

Airtight connection for 100 mm fans and filters

AC Infinity uses NBR nitrile rubber with a hardness of 65A. The material is flexible and conforms to the rigid device ports, helping to minimize leaks in the system.

A tight seal is particularly important in systems using a carbon filter, as air should flow through the intended ventilation path rather than seeping through gaps between individual components.

Steel Clamps with Screw-Adjustable Tension

The connector is equipped with two stainless steel clamps. After sliding the rubber element onto both ports, simply tighten the clamps to achieve a secure connection.

The screw mechanism allows for precise adjustment of the clamping force. The clamps can be tightened using a flathead or Phillips screwdriver, and specially shaped grooves in the rubber body help keep them in the correct position.

What devices is the AC Infinity AC-RCA4 compatible with?

This model is designed for installations using 4-inch / 10.2-cm connections. The connector can be used, among other things, to connect:

• a 100 mm duct fan with a carbon filter,
• a fan with a duct or ventilation pipe,
• a carbon filter with the rest of the system,
• two compatible ventilation duct components,
• HVAC system components of the appropriate diameter.

Before installation, make sure that the diameter of the connections on the devices being joined is suitable for the 4" coupling.

Why use a 100 mm flexible connector?

Using a rubber connector between ventilation components improves the seal of the connection while reducing the direct transmission of vibrations. Unlike a completely rigid connection, the flexible rubber can compensate for slight misalignments between individual system components.

The matte black finish also complements fans, filters, and other equipment used in modern grow box ventilation systems.

Technical Specifications

FAQ – AC Infinity 100 mm fan connector

Does the AC Infinity AC-RCA4 fit a 100 mm fan?

The AC-RCA4 model is designed for installations with a diameter of 4 inches, or approximately 10.2 cm. It can be used with compatible fans and other 100 mm components.

Can it be used to connect a 100 mm fan to a carbon filter?

Yes. This is one of the primary uses of this connector. It allows you to create a flexible and airtight connection between a carbon filter and a duct fan equipped with the appropriate outlet.

Does the rubber connector actually reduce noise?

Its flexible design helps isolate vibrations generated by the fan and reduces their direct transmission to the filter, ducts, and other system components. As a result, it can reduce noise caused by system vibrations.

Does the AC-RCA4 prevent air leakage?

When properly installed, the connector fits tightly against the connections, and the adjustable clamps further compress the rubber. This helps minimize leaks and airflow losses.

What is the AC Infinity connector made of?

The body is made of NBR nitrile rubber with a hardness of 65A. The two adjustable clamps are made of stainless steel.

How do you install the AC-RCA4 connector?

Slide the connector onto the ports of both components to be connected, position them correctly, and then tighten the screw clamps using a flathead or Phillips screwdriver.

Is the connector only suitable for grow boxes?

No. It can be used for ventilation in both grow boxes and grow rooms, as well as in other compatible ventilation and HVAC systems.
