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.

The Triton C-3 utilizes Pentair's fiberglass-reinforced tank construction with multiple internal diverters to improve water distribution through the filter media. Unlike the standard Triton C, the C-3 configuration features 3-inch flange connections for commercial plumbing applications.

Important: This filter is supplied without a multiport valve. The required valve or commercial valve arrangement must be purchased separately.

Specifications

Filter Media Requirements

Pentair specifies the following media for the TR100C-3:

• 150 lb Pea Gravel
• 450 lb Filter Sand
• 600 lb Total Media

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.

Confirm Before Ordering

Before purchasing, verify:
