FAQs

What is the main benefit of using this clamp over a standard one?+

The primary benefit is noise reduction. Its nitrile rubber construction absorbs vibrations from your inline fan and airflow, creating a significantly quieter grow environment compared to standard metal or plastic clamps.

Will this fit my 4-inch inline fan and ducting?+

Yes, this clamp is specifically designed to fit all standard 4-inch ducting, inline fans, and carbon filters. It's a perfect match for products like the AC Infinity CLOUDLINE S4 and other AC Infinity ventilation gear.

Are the clamps resistant to rust and corrosion?+

Absolutely. The included worm drive clamps are made from stainless steel, ensuring they remain strong and rust-free even in high-humidity environments.

How does this clamp improve airflow efficiency?+

By creating a completely airtight seal, the clamp prevents air from leaking at connection points. This ensures that 100% of the air moved by your fan reaches its destination, maximizing the efficiency of your entire ventilation system.
