Not much info to go on, but a simple "make yer own" comes to mind if the engine is a stationary unit. Assuming that "very low pressure" means not more than a few bars, and that flow velocity is also comparatively low, how about installing on the upstream side of the pump a simple t-fitting around 2 or 3 times the diameter of the circulating system lines. Orient the crossbar of the T vertically, inflow through the upright of the T, outflow through the bottom arm of the crossbar, and a vertical pipe/tube column tall enough on the top to contain a fluid column equivalent to your pump system pressure. By increasing the volume and dropping flow speeds at the inlet leg, included bubbles have time to migrate to the top of the flow and into the upright column. Since you said "very low pressure" I'm assuming you simply want to scrub physical bubbles and not to extract dissolved gasses. If your flow is exceptionally thick material, you may need a long overvolume inlet segment but aside from that it should work for a stationary rig, and the top of the column can be screened and capped but vented to ambient and never need any tapping of extracted airt at all. Not sure if the idea is at all applicable to your needs, but it's passive, cheap and what sprang to mind. Tiger

Thanks for the info, unfortunately it is quite a high flow rate system although the pressure only goes up to around 5psi so I belieive the air needs more time to migrate from the fluid.
