Product Lines

AFS Series Air Flow Pressure Sensing Switches

Cleveland Controls AFS Series switches perform electrical switching action at low positive, negative, or differential air pressures, covering sensing ranges through 12 inches water column. Available in fixed and adjustable setpoint configurations. Applied worldwide in commercial, industrial, and residential HVAC, boiler and burner control, and process monitoring. The AFS-271 is a general-purpose AFS model for air flow proving and differential pressure sensing.

RFS Series Specialty Sensing Switches

Cleveland Controls RFS Series covers application requirements where standard AFS configurations are not appropriate. RFS models address specific mounting geometry, pressure range, or switching configuration requirements for OEM HVAC equipment and custom industrial process applications. The RFS-4100 is one model in the RFS specialty line.

NS2 Series Switches

Cleveland Controls NS2 Series provides matched switch and component kits for specific HVAC equipment air flow proving circuit configurations requiring modified switch assemblies.

Why Contractors Specify Cleveland Controls

HVAC contractors and boiler technicians specify Cleveland Controls because the brand has been manufacturing air flow proving switches in the United States for over 100 years, and the AFS Series is a recognized reference for combustion air proving and draft monitoring in heating equipment. All products are designed and manufactured at the Cleveland, Ohio facility. The AFS Series covers the proving pressure ranges in residential and commercial HVAC and boiler equipment in fixed and adjustable configurations, distributed through HVAC and plumbing supply channels worldwide.

How to Choose a Cleveland Controls Switch

The most important decision variable is the pressure type and sensing range required: positive, negative, or differential, and the proving pressure specified by the HVAC equipment OEM. Fixed setpoint AFS models are used where the OEM specifies the proving pressure. Adjustable setpoint models are used where field setting is required. For filter status monitoring, AFS differential models sense the pressure drop across the filter, switching at the setpoint when the filter is dirty. For specialty OEM applications, the RFS Series provides alternative configurations.

FAQs

Where are Cleveland Controls switches manufactured?
All Cleveland Controls pressure sensing switches are designed and manufactured in the United States at 1111 Brookpark Road, Cleveland, Ohio. Cleveland Controls has been manufacturing air flow sensing switches in the United States for over 100 years.

What warranty does Cleveland Controls offer?
Warranty terms are available through authorized HVAC supply distributors.

What is the difference between the AFS Series and RFS Series switches?
The AFS Series covers general-purpose air flow pressure sensing for HVAC, boiler, and burner applications with fixed and adjustable setpoint options up to 12 inches water column. The RFS Series is a specialty line for applications where standard AFS geometry, pressure range, or switching configuration does not meet the specific OEM or process requirement.

What sensing range does the Cleveland Controls AFS Series cover?
AFS Series switches cover from low-level draft pressure through 12 inches water column in fixed and adjustable setpoint models. The full range by model is. For requirements outside the AFS range,

What HVAC applications are Cleveland Controls switches designed for?
Cleveland Controls AFS Series switches are applied in combustion air proving for gas furnaces and boilers, draft inducer proving, filter status monitoring, economizer damper proving, and process air flow monitoring in commercial, industrial, and residential applications.

Can a Cleveland Controls switch replace a competitor's pressure switch in an HVAC application?
Cleveland Controls AFS Series switches can often replace HVAC equipment pressure switches where the proving pressure, electrical rating, and connection configuration match. Verify setpoint range, switching configuration (SPST or SPDT), contact rating, and pressure connection type match the OEM specification before installation. Adjustable setpoint AFS models provide flexibility for field replacement applications.
