The Maintenance Sleeve Advantage
The STF-130 maintenance sleeve inserts into the outlet of the tank to block off flow, preventing built up solids and unfiltered effluent from exiting the tank when the filter is removed. This means that the septic tank owner doesn’t have to pay to have their tank pumped every time the filter is serviced (though tanks should be pumped on a regular basis for optimum performance). It also means that the system is always protected even when the filter is being serviced or inspected. Maintenance sleeve comes with 1/2” pvc coupling attached. Simply add your desired length of 1/2” pvc pipe to make the handle.

Flexible enough for just about any application. A very common application is in square concrete baffles. Instead of chiseling the concrete baffle out of the tank and installing a plastic baffle you can use our filters in the square, oval or just about any other shaped baffle as is as long as the baffle has not deteriorated. Commonly, these baffles are 5 inches square and our 7 inch red filter does a great job of filling this square. To determine the filter size that you need just measure the largest dimension of your baffle. In a 5 inch square baffle that is the diagonal of about 7 inches.

Sim/Tech bristle filters come in various sizes rated at different maximum flow rates. Large filters can be used for high volume commercial applications and/or filters can be manifolded together to meet the appropriate flow rate. The filters are rated at the following maximum flow rates in gallons per day: 4” (1800), 6” (3,000), 7” (4,000) and 8” (5,000).

The filter is composed of non directional polypropylene bristles that are would together with a 316 low carbon stainless steel core. The contoured shape of the filter creates a debris separation space that naturally sorts debris according to size and mass. This space also ensures even filter usage for a long lifespan.
Service intervals will vary depending upon many factors such as water usage, soap usage, garbage disposals, etc. The filter should be serviced at least every three years. For maximum protection it should be replaced about every 50,000 gallons of effluent. Because the water usage and configurations of systems vary quite a bit from area to area and even in the same area depending upon when a system was installed, it is recommended that the filter be inspected annually.
