DUCT CLIP 100mm-315mm

Description

DUCT CLIP 100MM–315MM is the adjustable metal duct clip designed to create secure, airtight connections between ducting sections, fan housings, carbon filter flanges, and silencer connections across the full range of standard duct diameters used in UK grow room ventilation systems. We have been recommending quality duct clips to UK growers since 2017 as an essential fastening component for building leak-free, professional-quality extraction systems.

Why Duct Connections Must Be Secured for Effective Odour Control

A ventilation system is only as effective at odour management as its weakest connection. A loose duct joint between the fan and carbon filter allows unfiltered air to bypass the filter entirely, rendering your odour control system ineffective regardless of how well-rated the carbon filter itself is. Loose connections also reduce system airflow by introducing turbulent air leakage that reduces the effective static pressure driving clean air through the filter media. The adjustable duct clip provides a secure, tightenable metal band that compresses the duct material uniformly around the fitting or spigot, creating an airtight connection across the full circumference. The adjustable range covering 100mm to 315mm makes this a versatile single-component solution for multiple duct sizes, reducing the need to stock multiple different clip sizes for different parts of the ventilation system.

Installation, Torque, and Best Practice for Duct Connections

Slide the duct clip over the duct end before connecting to the fan spigot, filter flange, or silencer inlet. Seat the duct fully onto the fitting — it should overlap the spigot by at least 30–40mm to provide adequate connection surface for a reliable seal. Position the clip over the overlapping section and tighten the screw mechanism evenly until the duct material is compressed firmly against the fitting without cutting into the material. For acoustic flexible ducting with a thicker wall profile, ensure the clip’s band width is sufficient to engage the full duct wall depth. Use duct clips at every connection point in the extraction system — fan outlet, filter inlet, filter outlet, and at any ducting join points. Pair with flexible rubber duct couplings at the fan connection for vibration isolation. Browse our full range of ducting, fans, carbon filters, and ventilation accessories.
