Dental lab gypsum filter and plaster powder trap designed for drainage systems to capture gypsum and stone particles produced during cleaning and prevent sewer blockages. Intended for installation below a drain basin with 50mm BSP inlet and outlet connections. Key benefits Prevents drainage blockages by capturing gypsum, plaster, and stone particles before they enter the sewer. Easy maintenance with removable lid, removable filter basket, and removable filter screen for quick cleaning and inspection. Controls surge flows with an internal surge flow baffle to reduce the chance of overflow during volume rinsing. Simple integration into existing dental lab drainage lines that use 50mm BSP connections. Main features Function: traps gypsum and plaster powder from rinsing and washing operations to protect downstream pipes and drains. Compatibility: designed for use in dental laboratory drainage systems, typically installed below a sink or drain basin. Compatible with 50mm BSP inlet and outlet connections. Size and connections: 50mm BSP inlet and outlet connections for standard plumbing integration. Maintainability: removable lid, filter basket, and screen allow for handson cleaning and routine maintenance without special tools. Performance: continuous filtration during cleaning cycles and controlled flow handling due to surge flow baffle. Typical applications Dental laboratories: installed beneath bench sinks used for washing casts and models to trap stone debris and prevent blockages. Prosthetics and model workshops: collects plaster and gypsum residue from cleaning stations and ultrasonic baths before it reaches the main drain. Small clinic or lab cleanup areas: fits under basins where frequent rinsing produces fine stone or plaster waste. Installation and maintenance notes Install in the drainage line below the basin using the 50mm BSP connections. Position to allow easy access to the removable lid for periodic cleaning. Regularly remove and empty the filter basket and clean the screen to maintain flow and prevent buildup. Inspect the surge flow baffle and seals during maintenance to ensure continued performance. This trap provides a practical, serviceable solution for managing gypsum and stone waste in dental and laboratory drainage systems while simplifying cleaning and reducing the risk of sewer blockage.
