I have just purchased V2-50 and I note that the recommended Gast compressor is oil free. Is this required, or can I use a standard oil lubricated compressor?
Hi @Hargie,
A standard oil lubricated compressor should be just fine. We simply suggest the oil free compressor for ease and simplicity. As long the compressor is providing plenty of dry air at the required pressure, it should work just fine.
Thanks!
Hi everyone,
Jumping on this thread since the title is right on point for my question. I’m curious as to what the actual air flow and resistance to air flow is on the V2-50 for a given back pressure. Basically, is there a lot of resistance to airflow or is it free-flowing?
The recommended compressor boasts:
0.9cfm (25.5lpm) @ 30psi (206kPa) or
1.9cfm (53.8lpm) @ 0psi (0kPa).
Compare this to a small air pump for the likes of inflating airbeds or rubber rings SUPPOU Electric Air Pump, 5200mAh Portable Air Pump with Fast Inflating/Deflating, Rechargeable Electric Pump with 4 Nozzles for Kids Paddling Pool, Swimming Pool, Airbed, Inflatable Boat (black) : Amazon.co.uk: Sports & Outdoors which boasts:
400lpm which is more than 10x the recommended compressor,
4kPa which is many orders (50x) less than the recommended compressor.
I actually have this small air pump and it’s used to blow chips away and offers a little air cooling on an old manual mill. Whether this would be suitable for the V2-50 really depends on how free flowing the air is.
The V2-50 does not provide much back pressure, the system is pretty much open and free flowing. The main source of back pressure is the 4mm air hose used to route the air into the machine and spindle.
This why we recommend a compressor/pump that has high storage capacity (so that it doesn’t have to run very often to keep up) or is rated for continuous flow.
Hopefully this helps!
