Product Overview

The Jandy SFSM140 Side-Mount Vertical Sand Filter provides high-capacity filtration for large residential pools and compatible commercial applications. Its durable laminated fiberglass-reinforced tank offers excellent resistance to outdoor conditions, operating pressure, and pool-water chemicals.

With a 7.06-square-foot filtration area and maximum flow rate of 141 GPM, the SFSM140 can support up to 50,760 gallons during a six-hour turnover cycle. The side-mounted plumbing configuration uses industry-standard connection spacing, making the filter suitable for new installations, equipment upgrades, and replacement of many existing side-mount sand filters.

The tank arrives with the internal lateral and diffuser assemblies installed, reducing on-site assembly requirements. A combination sand-and-water drain, clean/dirty pressure-gauge indicator, manual air-relief valve, and serviceable internal plumbing help simplify operation and routine maintenance.

Benefits

High-Capacity Filtration

The SFSM140’s large filtration area allows water to move evenly through the filter media, capturing dirt and debris while supporting high-flow pool systems. The filter is rated for up to 141 GPM, provided the plumbing, pump, backwash valve, and other equipment are properly sized.

Actual allowable system flow may be limited by:

• Pool plumbing size
• Pump performance
• Backwash-valve rating
• Heater flow requirements
• Sanitizer or automation components
• Local commercial-pool codes
• Maximum equipment-pad pressure

The filter should never be operated above its published maximum working pressure.

Durable Fiberglass-Reinforced Tank

The filter tank is constructed from laminated polyester and fiberglass resin for strength, longevity, and resistance to outdoor pool-pad conditions. Its robust molded base provides stable support and includes locations designed for anchoring the filter to the equipment pad where required.

The internal lateral and diffuser plumbing is modular, allowing components to be serviced or replaced without replacing the complete tank.

Easy Maintenance

The SFSM140 includes several service-friendly features:

• Clean/dirty indicator on the pressure gauge
• Manual air-relief valve
• Combination sand-and-water drain
• Accessible side-mounted plumbing
• Serviceable internal lateral and diffuser assemblies
• Compatible backwash-valve options

The clean/dirty pressure indication helps operators identify when backwashing is required, helping avoid unnecessary water use and maintaining efficient filtration.

Specifications

The SFSM140 measures 49.7 inches high by 37.5 inches in diameter and is rated for a maximum working pressure of 50 PSI.

Warranty & Compatibility

Union Information

The filter connects using two Jandy 2" × 2½" unions.

Important: Jandy’s standard SFSM140 literature lists these unions as not included with the base filter. This listing should state that unions are included only when Pool Supply Depot is supplying them as part of this specific bundle.

Filter Media

The SFSM140 is designed for use with properly graded pool-filter sand or another NSF-approved filtration medium that is compatible with the filter.

The correct media quantity and freeboard level must be followed during installation. Do not overfill the tank, as improper media loading can restrict backwashing, increase system pressure, and reduce filtration performance.

Filter media is sold separately unless specifically stated otherwise.

Confirm Before Ordering

Verify the following before purchasing:

• Required model is SFSM140
• Equipment pad can accommodate a 37.5-inch-wide tank
• Adequate overhead and service clearance is available
• System flow will not exceed 141 GPM
• Pump can provide at least 105 GPM for proper backwashing
• Plumbing matches the required union configuration
• Correct Jandy backwash valve has been selected
• Filter-media type and required quantity have been confirmed
• Equipment pad can support the filled filter
• Local residential or commercial pool codes are satisfied
• Your specific package includes unions when advertised as “with unions”

Installation Information

Installation should be performed by a qualified pool professional. The filter must be installed on a stable, level equipment pad with adequate access for servicing, draining, media replacement, and backwashing.

The pump must be shut off and all pressure completely relieved before opening, servicing, or loosening any filter component. Never adjust the clamp, pressure gauge, air-relief assembly, plumbing, or drain while the system is pressurized.

Proper backwash flow is essential. The SFSM140 requires a minimum backwash flow of 105 GPM for effective cleaning of the filter bed.

Warranty Information

This genuine Jandy product is covered by the applicable Jandy/Fluidra manufacturer warranty when purchased through an authorized dealer and installed according to current manufacturer requirements.

Professional installation may be required for full warranty eligibility. Damage resulting from excessive pressure, incorrect plumbing, improper media, inadequate backwash flow, freezing, chemical damage, improper installation, or operating the filter outside Jandy’s published specifications may not be covered.
