Backdraft dampers are made of galvanized steel and prevent air leakage into your fan setup. They are easy to install, fit directly onto the ducting, and prevent a back draft of air when the fans are switched off. They also save CO2 and prevent odors from flowing backwards. Silencers reduce noise from fans and carbon filter systems, are easy to hang with lightweight aluminum construction and, do not rust! The best location is as close as possible to the source of noise. Find the duct damper, duct muffler or duct silencer you need in a wide range of sizes. Come check out our large selection of noise killing devices! Our dampers help you control both hot and cold temperatures in individual rooms. We offer the highest quality silencers and mufflers. Phat mufflers offer 85% noise reduction in your grow space. Suncourt mufflers offer easy installation straight into your ductwork without impeding your airflow.
Website states orders are processed 1-24 hours, here we are a week later & there has been no updates or tracking information. I called & canceled my order & will no longer do business with HydroBuilder, spoke with two different people on different occasions & neither could give any information & did not offer any solution.
Hi, I purchased 125 20 gallon bags for our Loofah's here at our farm. As of this Friday, it will be 4 Weeks and they let me know it went back to the warehouse. 4 Weeks later.
Delivery is supposed to be next Monday, I have no faith in that. I recommend you find a more reliable source where you live. I am here in Michigan where this product was sent out. All the way to California, "by Mistake" Chelsea said.
Save your time and money and shop local.
From locating the product through receipt of package, the whole process was well organized. Shipping cost was reasonable and delivered quickly. THANK YOU!
NEVER shop here, they didn't send the right product, and are now insisting that we pay $100 restocking fee + $60 on shipping (meaning we don't get any money back).
I will never recommend or shop here again.
