After a very comprehensive study on portable suction units and there setup we have decided to remove filters from the units. We have mostly LSU (laerdal suction units) attached to crash trolleys the lsu is very tight for space and does not allow for the filter to be attached without leaks. From the checks with have completed the loss of suction and the ability of some staff to replace the filter correctly reduces the LSU's suction considerable. Adding to this we are constantly getting calls on poor suction. What about the unit and damage to the motor well we havent had any (so far). The number of calls has reduced and there has being very few queries on suction strength.
