Product Overview
The Pentair Triton C-3 TR100C-3 High Capacity Sand Filter | 140310 is a commercial-grade 30-inch fiberglass side-mount sand filter designed for high-flow swimming pool filtration applications. With 4.91 sq. ft. of effective filtration area and flow rates up to 98 GPM, the TR100C-3 is built for commercial pools and demanding aquatic facilities requiring dependable filtration and durable construction.

Filter Media Requirements
Pentair specifies the following media for the TR100C-3:

Proper filter-grade media must be used according to Pentair's installation instructions.
Valve Sold Separately
The Pentair 140310 TR100C-3 does not include a multiport valve.
The C-3 version uses 3-inch flange connections, so the valve and plumbing arrangement must be selected according to the commercial installation requirements.
Do not assume a residential Triton side-mount valve will connect directly without verifying the required flange and plumbing configuration.
Installation Information
The TR100C-3 should be installed on a solid, level equipment pad with adequate clearance for servicing and sand replacement.
Installation should account for:
- 3-inch flange plumbing connections
- Required flow rate
- Pump performance
- Backwash flow requirements
- Drain capacity
- Available vertical clearance
- Required commercial turnover rate
Commercial installations must also comply with applicable state and local health department requirements.
