The new manual screen changer addresses several problems of the older design. It offers:

• Easy access to the screens by swinging them out completely
• Full 360 degrees circular heaters (without the half-moon cut-outs)
• Less space requirements because of the ratchet type handle
• No need for an additional flange since it mounts directly onto the barrel flange
• Easy removal of the complete unit because it is bolted from the front
