Question about Gaggenau VL051707 Hob Ventilator: AS 081-051 Connecting Element to fit GB 031-707 Kitchen Hood

1 Answer

Is the Gaggenau VL051-707 compatible with any other fans?

And, what is the CFM?

I bought the Hob Ventilator and am trying to find options for the fan (if any). I also can't seem to track downt the CFM for the GB 031-107, which is the prescribed unit. It says it can be mounted remotely (outside wall), but I'm hesitant to put it 20 ft away unless I know it has a decent CFM rating...

    FIrst, thanks Master_Tech. I'll mount mine in the crawl space, but away from the kitchen. Do you know if any other fan might work? Something that is not $1200? I was wondering if one of the Bosch units might work. Made by the same company and hundreds less.

    BTW, I picked-up a used on (freak-find) for $25. Works great and saved over $1000.

Not really due to the wiring you will have to rewire the unit see the power in and control power to the ventlator comes from the countertop unit.. unless you rewire it. See the black molex plug under ventlator that is the connection

Switch is probably faulty, or wire / connection to switch. If switch and wiring test ok trace wire from that button back to wherever it goes and look there for fault.

Repair man replaced the switch & the relay and the motor still won't start up.

Check for power at the motor...if there is no power then the switch and relay are faulty or wired wrong...
if there is power to the motor then the motor is bad...

Cold air is coming in from outside, didn't do this before.

Look up into the duct if possible. There should be a damper in the duct called a "backdraft damper" that closes and prevents cold air from entering the duct when the fan shuts off. The damper could also be located near the outlet of the fan which could be a wall or near the roof level (maybe in the attic if it goes through there).

I have a dayton kitchen exhaust blower mod no. 4hz65, 1/25 hp, 1550 rpm, 115 volts, 1.5 amps, 8 inches. it does not seem to do the job, do i need a stronger one?

Remember air will only move as fast as the size of the exhaust pipe in relationship to the fans ability to push. Make sure yours is the proper size for the fans volume.
