About Product Overview

The Turbine BS 14" Mill vent from Air Vent's Air Hawk line uses wind, not electricity, to pull hot, stale air out of your attic. As outside air moves across the roof, the turbine head spins and draws air up and out through its vents, working harder as the wind picks up and keeping steady airflow even on calm days.

Built from aluminum in a mill finish, it's made to handle sun and weather without paint or stain. It fits roofs from a 3/12 to a 12/12 pitch, so it works on everything from a low-slope ranch to a steep-pitched two-story. With 132 square inches of net free area, it moves a real volume of air per unit installed, which matters when you're figuring out how many vents your attic needs. Note that it doesn't come with a bird screen or wildlife guard, so plan for that separately if pests are a concern in your area.

  • Height: 21.3 inches

  • Net Free Area: 132 sq. in.

Price check

Go ahead. Check.

You're going to price-check us against Amazon, Home Depot, and Lowe's. Everybody does. Good — open all three tabs. We'll wait. Then look hard at what you're actually being handed over there.

On Amazon, start with these four questions before you click buy.

01

Who's actually selling it

The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.

02

Whether the warranty survives

Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Air Vent. A third-party marketplace seller usually isn't.

03

Where the box came from

Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

04

Who you call when it breaks

Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556

The big boxes don't care if your hardware store survives.

Amazon, Home Depot, and Lowe's are built to pull every hardware dollar out of your town. When the local shop can't keep the lights on, the counter where somebody actually knew which part you needed goes with it. We're built the other way: real brands so you're never stuck on a marketplace, and a straight answer to buy it down the street when that's the better call. Support independent hardware — it doesn't restock itself.

Why we tell you to shop local

Shop Local · Support Independent

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
