Product Overview

The Jandy SFSM100F Commercial Side-Mount Vertical Sand Filter is designed for high-use residential and commercial swimming-pool applications requiring dependable filtration, high flow capacity, and durable construction.

This model provides a 5.0-square-foot filtration area with a maximum flow rate of 100 GPM. At its full rated flow, the SFSM100F can support up to 36,000 gallons during a six-hour turnover cycle. Its side-mounted plumbing configuration uses 3-inch ANSI-150 flange connections, making it suitable for commercial equipment rooms and other installations using flanged plumbing.

The tank is constructed from laminated fiberglass-reinforced polyester with UV protection for strength and long-term outdoor performance. A serviceable radial-seal lid, oil-filled pressure gauge, internal diffuser, lateral assembly, large media capacity, and combination sand-and-water drain help simplify installation and ongoing maintenance.

Specifications

Jandy rates the SFSM100F at 100 GPM, 50 PSI maximum operating pressure, and 75 GPM minimum backwash flow. The tank measures approximately 32.5 inches in diameter and 41 inches tall.

Commercial-Grade Filtration

The SFSM100F is engineered for pools with demanding circulation and filtration requirements. Its large filter bed distributes water through the media to capture suspended debris while maintaining efficient system flow.

The filter may be appropriate for:

• Commercial swimming pools
• Hotel and resort pools
• Apartment and condominium pools
• Community and HOA pools
• School and institutional pools
• Therapy pools
• Large residential pools
• High-use aquatic facilities

Final filter sizing must be based on the required turnover rate, pool volume, pump performance, plumbing design, local health-code requirements, and the flow limitations of all connected equipment.

3-Inch ANSI Flange Connections

The SFSM100F uses 3-inch ANSI-150 flange connections for the inlet and outlet. This flanged configuration is intended for commercial plumbing systems where secure, serviceable connections are required.

Important Flange Information

Jandy’s published specifications identify the SFSM100F as having 3-inch ANSI-150 flange connections but state that the flange connection kits are not included with the standard filter. Advertise this model as “with flanges” only when the required flange kits are physically included in your Pool Supply Depot package.

Jandy ANSI-150 flange kits are available separately for compatible SFSM commercial filters.

Filter-Media Requirements

The SFSM100F may be filled using either a sand-only configuration or a properly layered sand-and-gravel configuration.

Sand-Only Configuration

• Approximately 679 pounds of approved filter sand
• Required freeboard: approximately 15 inches

Layered-Media Configuration

• Approximately 120 pounds of pea gravel
• Approximately 558 pounds of approved filter sand
• Required freeboard: approximately 15 inches

Filter media is not included unless specifically stated in the listing. Always use correctly graded, approved pool-filter media and follow the manufacturer’s filling procedure.

Turnover Capacity

At the maximum rated flow of 100 GPM, the SFSM100F provides the following theoretical turnover capacities:

These figures are mathematical flow calculations and do not replace professional filter sizing. Commercial pool codes may require a shorter turnover period or additional filtration capacity.

Backwashing Requirements

The SFSM100F requires a minimum backwash flow of approximately 75 GPM to properly expand and clean the filter bed.

The pump, drain line, backwash valve, waste plumbing, and discharge location must all be capable of sustaining the required backwash flow. Inadequate backwashing can cause:

• Compacted filter media
• Reduced water clarity
• Channeling through the sand bed
• Increased operating pressure
• Shortened filtration cycles
• Reduced filter performance

A compatible commercial backwash-valve assembly is sold separately.

Durable Tank Construction

The filter body uses laminated fiberglass-reinforced polyester construction with UV protection. This construction provides strength, corrosion resistance, and durability in outdoor commercial equipment environments.

The SFSM series also incorporates:

• A smooth exterior finish
• UV-protected ABS and glass-filled nylon lid components
• Adjustable radial-seal lid design
• UV-protected molded base
• Equipment-pad anchoring provisions
• Serviceable internal components
