Designed for compact work spaces, Prima 440 and Prima 445 are ultra compact, portable anaesthetic machines for induction or operating rooms where space is at a premium. While Prima 440 is a table top model, Prima 445 is a rail-mounted model and both of them use a proven flow tube control system to deliver accurate concentrations and flows of anaesthetic gases into a patient breathing system. Each model comes with a single-station backbar for use with a Sigma Delta, or other Selectatec® compatible vaporizer.
