So I’m having a real hard time finding this fitting so I can attach a hose to the vent outlet. Does anyone have a link or can give me the diameter and pitch?
I think the thread is slightly less tha a 3/4 but more than a 5/8ths. Not something home depot or general big box stores carry and the filter I saw online is roughly $70.
I would go to a box store and buy a variety of different plastic fittings that are threaded on one side and barbed on the other. Pick which one fits the best and screw it into the exhaust port, attach a hose, and seal it all with sealant tape.
I believe it is 5/16 UNC threads. Good luck finding anything that fits. Your best luck is the hydraulic section of a technical wholesaler.
I usually offer the right connector with the pump. If all else fails, contact me.
Thanks but that didn’t work to well. I already tried attaching something with tape. The heat/oil vapors pretty much eat any tape I have. I tried the grey, the black, and the yellow from airtech. The yellow is rated at only 250f but the others are supposed to be 400.
I may be hitting you up but shipping from Europe would probably be hefty. I’m going to check out a refrigerator/hvac warehouse and also a plumbing supply store when I have a day off.
I do believe it is metric since it’s not fitting anything though.
That I think is for the hose hook ups for the inlets. The pump itself usually comes with something like that already attached. I’m talking about the exhaust part. In pictures it’s usually plugged but the plug has to be removed when operating to vent the pressure and fumes from the pump.
I may just call robinair Monday, but I’m just going to guess they’ll just try and sell me a filter that costs half of what my pump was.
Ok, now I understand, the question isn’t so easy …

OK, the outside.
The exhaust filter I found for other pumps are some 30 euro or so, but I have no idea if these fit other pumps.

Hmm yeah that’s pretty much what I’m looking for. That will be around 50-60 usd with shipping probably.
I’ll shop around here locally when it becomes a huge issue or when I have spare time. I guess I’ll just keep my pump by a window with an exhaust fan that I’ve been using.
By outlet on the Robinair you mean the exhaust hole on the handle?
My pump does vent oil vapors out that hole when the pump heats up.
You could turn a piece of delrin or plastic down on a lathe, thread one end for a barb fitting and press if it in there. Im not sure if adding backpressure to the exhaust would affect the performance of the pump though.
Thanks for the advice everyone. This problem happened when I left the pump on during a lamination test. I have since refused to do lamination using this pump.
The pump doesn’t exert much vapor if any when it’s running and pulling a full vacuum with no leaks so I’m not worried anymore about it.
I guess I had a solution of tapping the plastic plug and threading that with a barb fitting, but then there’s the little gap that still needs to be filled which could be filled with some type of bonding agent or filler I assume, or maybe a type of o ring gasket if it’s fitting enough.
Do you think that could make a filter with a bottle filled of activated carbon?
It can easily be done much better, It’s to show the concept.

Then, make a filter with active carbon, isn’t a good idea?
A greeting
I think it’s a good idea. But like I said earlier. As long as there’s no leak or it’s very very minor then the pump fumes aren’t an issue really. I’ll just deal with it if it becomes an issue down the line.
