Allied Medical LLC 12-20-3000 is a critical safety attachment designed specifically for Vacutron suction regulators. It acts as a secondary safeguard to protect the regulator and the central hospital vacuum system from accidental contamination caused by canister overflows. This model features a DISS hand-tight inlet, allowing for quick, tool-free installation and removal directly onto the suction regulator. The internal mechanical float is engineered to automatically cease suction if fluid enters the trap, ensuring that biological contaminants do not bypass the collection system. Its reusable design allows for thorough cleaning and sterilization, making it a cost-effective and essential component for maintaining hygiene and equipment longevity in clinical suction applications.
