Unclamp your feed line slowly, let the resin move up to the clamp, then clamp it again. Wait about a minute or so for the air to move through before starting the infusion.
What do you mean by air pockets? If you're talking about anything larger than pinholes, then something must be going wrong. I never degass my resin, and even then I only rarely have issues with pinholes, certainly never anything larger. The only time larger issues occur is when the bag loses vacuum or there is bridging.

To Hanaldo.
Thanks will try, the pockets that have came in can only be through trapped air/gas. The majority of laminate is prefect, no pinholes. Just the odd void.
The Fibre, materials and bag is all correctly in place, with no bridging. Part full infused, so i can only conclude that the one or 2 air pockets stem from air coming in with the feed.

how many layers of reinfircement do you have? perhaps your resin front upon infusion is travelling too fast across the part and not fully able to saturate the whole thickness of the reinforcement by the time it has passed by trapping a bubble.... although I would suspect much more entrapment if this was the problem...
