Vent-A-Hood cleaning for Magic Lung blowers

Why is Vent-A-Hood different?

No filters. That’s the whole thing, and it changes every step. On a normal hood the grease meets a baffle or a mesh screen first, and the blower behind it stays fairly clean. A Vent-A-Hood skips the filter and uses the blower itself as the separator. The Magic Lung wheel spins fast, the air makes a hard turn through it, and the grease can’t make the turn. It flies out against the wall of the housing and stays there.

Which works. It’s why the people who own them like them: a clean Magic Lung pulls hard and runs quiet, and there’s no filter to forget. The catch is the housing. It’s the filter, and it’s out of sight. A Vent-A-Hood can look spotless from the kitchen and be carrying years of grease in a spot nobody’s opened. In our experience the owners who love their hood most are the ones who’ve never seen inside the blower.

How do we clean a Magic Lung blower?

We take it apart. Every blower housing comes off the hood, and on a wide hood that’s two, three or four of them. The wheel comes off the motor shaft. Then each piece is steam-cleaned on the counter, the housing inside and out, the wheel fin by fin, and hand-detailed until it’s bare metal. Steam does the work; no harsh chemical would be safe on the motor face anyway.

While the housings are off we clean what they were hiding: the motor faces, the canopy, the lamps and lenses, and the collar where the hood meets the duct. Then it all goes back, each wheel seated and spun by hand before the power goes on, and we run every speed and listen. A Magic Lung put back right sounds like nothing at all.

The range underneath gets covered before any of this starts. The Vent-A-Hood in the photo above sits over a Capital range with open burners and a center griddle, exactly the kind of top that fills a hood fast, and the last place you want grease dripping mid-job.

How to check a Magic Lung yourself

Pull one housing. They’re made to come off without tools, which is the nicest thing about this hood. If the inside is a thin film, wipe it and leave it alone. If it’s a layer you can scrape with a fingernail, book the visit. That’s the same judgment we use on the standard hood cleaning visit for any other hood; the difference is that here you can’t read it off the filters, because there aren’t any.

Honestly, what fills a housing has almost nothing to do with the calendar. A kitchen that sears, fries or runs a griddle most nights packs one fast; a weekend house barely touches it, and both hoods look identical from below. So we don’t put a number on it. We open a housing, show you what’s in there, and set the schedule with you.

Can you run a Vent-A-Hood without cleaning the blower?

You can, and people do for years. The hood keeps pulling, a little less each season, and the sound creeps up so slowly nobody notices until it’s a rattle. Grease on the wheel is weight on the wheel. Weight out of balance is what the motor’s bearings feel first, and a cleaned wheel spinning true is the plain reason a Vent-A-Hood lasts longer. That’s the one part of this job you feel rather than see.

There’s also a point of no return. A housing that’s been ignored long enough has grease that’s gone hard and brown. Steam still gets it, but the finish under it sometimes doesn’t come back to new, and we’d rather say that before we open it than after.

Other hoods with similar blower designs

Most hoods put a filter in front of the blower, so this process is mostly for Vent-A-Hood. There are exceptions we treat the same way: custom liners with a bare squirrel-cage blower behind a light mesh screen, and older pro hoods where the filter is more decoration than barrier. In both cases the housing is doing the catching, and the housing comes off.

Where the blower sits matters too. Some liners push the wheel up into an inline or rooftop blower, and then the accessible duct above the blower is where our work reaches, or doesn’t.

The range under all of it is its own job, and so is the region. We service Vent-A-Hoods in estate kitchens on the New Jersey side and in the North Shore waterfront kitchens we cover, and every appliance brand we work on has its own notes one page over.

Send a photo of the underside of your hood. If we can see the housings, we can tell you what it needs, and the price fits in the same reply.
