Blower for Flammable Vapors ??

Blower for Flammable Vapors ??

Looking to convert a 2000 CFM Blower unit to be able to safely evacuate PVC Cement fumes in a production atmosphere.  Can I use an explosion proof squirrel cage motor or just a TEFC motor.  Of course, the wiring and switches will be all liquid tite or remote to the fumes.

RE: Blower for Flammable Vapors ??

You need an explosion proof motor and a fan with an anti spark facility.
There are many suppliers including Woods Ltd., Nu Aire Ltd., Vent Axia, Buffalo Forge etc.

Make sure your controls and wiring are explosion proof too.

You could also use a natural gas or diesel generator set as your exhaust fan. This will get rid of the volatile hydrocarbon pollution problem quite nicely.

Some of the electrical utilities are more amenable to cogeneration particularly since it saves them the cost of building more power plants. Generator set manufacturers such as Cummins have packaged cogeneration switchgear that make safe interconnection with utilities a lot easier.

You can also buy the industrial gensets as low a 20 kilowatts with oversize gnerators. The primary purpose of an over size generator is to allow a zig-zag connection the will give full single phase power. ON three phase the oversize generator can be used to provide extra reacitve power. Remember that when cogenerating you not only need to correct your own power factor you also might need to correct somebody else's power factor or provide the utility with reactive compensation for your distribution circuit.
