What is recommended for Air Assist for the 7 watt j tech laser

Can any one recommend an air assist compleate kit with air compressor and where to purchase it for the 7 watt j tech laser?

Probably not what your looking for, but I set a box fan in front of the machine when I use the laser. Not the best way of doing it, but it works in a pinch.

I have a ventilation system for the laser . I thought the air assist would help with cut outs ( make the laser a little more efficient in cutting stuff out) ??
