Aero-Fan Poly Air Sock PS-4 - 4 in x 400 ft - LDPE Air Duct Sock

Gentle, Even Airflow Along the Canopy - 400 ft Roll

Air blowing straight from a vent or fan can create uneven spots and stress plants. This poly air sock spreads air through evenly spaced holes along its length, so airflow is softer and more consistent across the growing area. The holes are 0.5 in across and sit 16.5 in apart, and the sock is made from durable, odorless LDPE.

This listing is one 4 in diameter roll holding 400 ft of duct sock. It suits growers who need long runs of distribution ducting, such as multi-row indoor rooms, and growers who plan to cut the roll into several shorter runs.

Frequently Asked Questions

Q: What does a poly air sock do?
A: A poly air sock is a fabric-like tube that carries air from a fan or duct and releases it through small holes along its length. This spreads airflow over a wide area instead of blowing it from one point.

Q: How is it different from rigid ducting?
A: Rigid ducting usually moves air from one point to another. A perforated sock also distributes air along its run, which helps reduce strong direct streams on plants.

Q: How far apart are the air holes?
A: The holes are 0.5 in across and spaced 16.5 in apart. This regular pattern spreads air evenly along the sock.

Q: What is LDPE?
A: LDPE stands for low-density polyethylene, a flexible plastic. Here it is durable and odorless.

Q: How much comes in one unit?
A: One unit is a single roll of 4 in diameter sock measuring 400 ft. The product is sold each.

Q: Is there an installation guide?
A: Yes, an installation guide PDF for the air sock is available. Check it before hanging the sock to confirm setup steps.
