Frequently asked questions
Does this filter ensure high-quality air filtration?
Yes. This RPI cartridge filter features an 11-micron filtration rating, which is specifically engineered to effectively capture particulate matter in plaster vacuum systems, ensuring optimal performance and air quality.
Is everything I need for installation included?
Yes, it is designed for a seamless, immediate installation. Each order is supplied complete with the necessary O-Ring, so you have all the required components to secure a proper seal right out of the box.
Is this a reliable replacement for Stryker equipment?
Absolutely. This filter is part of RPI’s exclusive line of high-quality components designed to fit the Stryker 900 Series CastVac™ equipment, specifically the Stryker 986 Plaster Vacuum model, where OEM parts may be difficult to source.
What are the exact dimensions of this cartridge?
To ensure a precise fit within your vacuum canister, the filter measures:
- Diameter: 7.00 inches
- Length: 11.38 inches
Is this filter built for durability?
Yes. It features a robust, industrial design with:
- A large surface area provided by vertically oriented pleats.
- Structural support bands that secure the pleated media, ensuring the filter maintains its shape during operation.
Is this filter compatible with the Stryker 986 unit?
Yes, it is specifically engineered for use with the Stryker 986 Plaster Vacuum (Stryker 900 Series CastVac™). It serves as a direct functional replacement for the OEM part number 986-500.
How should I maintain suction performance?
Maintaining suction performance is critical in plaster dust management. Using a factory-new, high-efficiency filter like this one ensures that your vacuum canister maintains proper airflow and that dust is effectively trapped rather than recirculated.
Are there any specific maintenance tips for this filter?
Because this is a specialized filtration component, we recommend routine inspection of the O-Ring seal whenever you replace the cartridge. Ensuring this seal is properly seated is the key to preventing leaks and maximizing suction efficiency.
Is this a factory-new replacement part?
Yes, all RPI STF044 cartridge filters supplied are Factory New, ensuring you receive a pristine, unused component ready for immediate integration into your laboratory or medical vacuum system.
Does this filter handle plaster dust effectively?
Yes. The unit is specifically designed for plaster vacuum applications, utilizing an 11-micron filtration standard that is capable of managing the fine particulate produced by plaster-based cast removal and other laboratory grinding processes.
