6' Fume Hood

[glondor]

The door should never be shut while working. You need an opening to draft thru. Closing at the end of the day is good when blower is off.

How are commercial fume hoods constructed for incoming air?

Does the blower switch off if the door is shut?

I strongly recommend anyone who wishes to build a fume hood to read this.

So you do need a horizontal opening along the bottom of the door. Essentially the door never does shut completely. And a glass door is the proper choice.

An interesting document Noxx, Thanks.

A few more pics:

Notice that this frame is not touching to the ground. There is 0.5'' of clearance.

The blower is ordered (Plastec30, 2HP - 2500CFM) and I ordered an AC drive to control the power.

For those who don't know, an AC drive (Variable-frequency drive) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.

I bought this one:

My blower works on 230V three phases but I only have one. Fortunately, this little device can operate on 1 phase and output 3 phases!

Very nice Noxx. The hood looks good. Where did you end up getting your blower? Do you have a link?

 

[Noxx]

What is the pickup truck for? Is it going to be a mobile fume hood?

Installed the butterfly damper on top of the hood.

Nice job Noxx.

Looks like you majored in chemistry and minored in carpentry!

A nice package was waiting for me to pick up today.

It's the Plastec blower!

Installation will begin tonight.

It's the Plastec blower!

That really sucks!

(Sorry I couldn't resist) :lol:

This "fume processor" works for 99.999% of refiners (400 oz a day or less):

Two plastic drums full of plastic balls and soda ash are not included in the $70 price tag. :shock:

Noxx likes to hunt flies with elephant guns. :lol:

First power up of the blower (no air ducts):

Very nice, Noxx. Variable speed? I could have used that feature to great advantage during the winter months, when evaporating. I think you're going to enjoy the setup.

What is the maximum CFM of the blower? How expensive is the Plastec blower? I'm sure you will enjoy a long life with minimal maintenance from the blower. And once the ducting is complete, it will quiet down considerably.

Hey Noxx I wonder if that budlight can in the last cabinet pic adds to on the spot creativity :lol: :lol: :lol: :lol:

No Budlight for me friend, I don't like light beer. It's a Bavaria, straight from Hungary.

What is the maximum CFM of the blower? How expensive is the Plastec blower? I'm sure you will enjoy a long life with minimal maintenance from the blower. And once the ducting is complete, it will quiet down considerably.

The Plastec30 blower is rated at 3500CFM @ 2HP (0'' H2O) or 2500CFM @ 2'' H2O. It is considerably more than what I need but it will also operate another hood for my propane furnace. Both need to run simultaneously.

The blower is around $1500 CAD here, maybe slightly cheaper in the US.

 

[glondor]

Where did you source the blower Noxx. If it is $1500 it is a good find for sure. NIce cfm rating as well.

 

[Noxx]

I contacted Plastec and they referred me to Master. They have offices near Montréal. It was a special order and there's a two weeks delivery time.

that really is a quiet running blower, not at all what i was expecting to hear. and with the duct work hooked up i doubt you will hear that much noise.
