When packing things like clothes and sleeping bags there are plastic bags with a one way valve you hook up to a vacuum cleaner ad suck out the air. This protects the clothes from dampness and keeps them fresh. This can also be done with the seal a meal vacuum packing machines. I’ll add two poor man versions. Both use generic ziploc style bags. The first is used on bulky items like clothes that will not be damaged by being crushed. Stuff the bag, place on a hard surface, cover with a board [like a square of plywood] and sit on it. When the air is squeezed out seal the bag. The final method requires an adapter. The adapter sizes the hose on your vacuum cleaner down to a cocktail stirrer straw. You want this small size straw so it is less likely to collapse when the vacuum is drawn and it makes it easier to seal the bag. The adapter can be a cork, rubber stopper, rolled up tape or anything that will form a seal. You will want to off set the straw to near the edge. This will make it easier to work on flat surfaces. Pack the bag. Insert the straw. Seal the bag except where the straw enters. Place on a firm surface. Place a thumb or finger over the straw over the bag seal. Turn on the vacuum. When the air is removed quickly pull out the straw. At the same time press down and seal the bag. This method works nicely for items that could be damaged by the squeeze method. This method could work with your refer compressor. Learned that trick from this device. http://www.pump-n-seal.com/
The Pump-N-Seal may be cheap and look like junk but they do work.
