Allied Medical LLC 12-20-1000 is a critical safety attachment designed specifically for Vacutron suction regulators. It acts as a secondary safeguard to protect the regulator, wall outlets, and the central hospital vacuum system from accidental contamination caused by canister overflows. This trap features a DISS nut and nipple inlet for a secure connection to the regulator and a standard hose barb outlet for tubing. 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.
