Ventilation Timers

Fan Timer Switches for Efficient Ventilation Control

Fan timer switches are a practical solution for maintaining proper ventilation across commercial spaces, from restrooms and locker rooms to maintenance areas and warehouses. These controls ensure exhaust fans run only as long as needed, improving air quality while keeping energy use in check. By automating fan shut-off, timer switches help reduce utility costs, extend equipment life, and support compliance with ventilation and building standards. Available in mechanical, digital, and smart models, they integrate easily with existing systems to provide consistent, energy-efficient airflow management in any facility.

What Is a Fan Timer Switch?

A fan timer switch is an electrical control device that manages how long a fan operates after it’s turned on. Commonly used in commercial and industrial ventilation systems, it allows facilities to maintain proper airflow without wasting energy. Once activated, the timer runs the fan for a preset duration, then automatically shuts it off. Fan timer switches come in several formats, including mechanical dial timers, digital countdown switches, and programmable smart controls that can connect to larger building automation systems. This simple control adds efficiency, reduces maintenance costs, and helps ensure consistent ventilation across work areas.

Benefits of Installing a Fan Timer Switch

Adding a fan timer switch to your facility’s ventilation system delivers measurable savings and better environmental control. By limiting fan run time, these switches cut unnecessary energy use and lower operating costs. They also help prevent humidity buildup that can lead to mildew, corrosion, or equipment damage. In restrooms, locker rooms, or kitchens, timed ventilation keeps air quality consistent and odors under control. For property managers and maintenance teams, fan timer switches simplify compliance with energy efficiency standards and reduce the need for manual monitoring. It’s a small upgrade that keeps your air systems running smarter and longer.

Fan Timers, Switches & Controls

Leaving the bathroom fan on after your morning shower can be a tricky proposition. Studies show that turning the fan off after less than 20 minutes increases the risk of long-term mold build-up, which can cause considerable property damage and respiratory distress. But many of you know the feeling of keeping the fan on and then forgetting all about it, leading to hours of wasted electricity and energy. An exhaust fan timer switch from Conservation Mart solves this problem by leaving the fan on for a set amount of time – even if you turn the light off – to clear the room of moisture without driving up your utility costs.

Find mechanical ventilation control devices that allow you to set the timer when you step in the shower along with digital fan timers with delay settings for use with hot tubs and spas. Most timers can be set for up to 60 minutes so you can clear particularly humid areas. We also carry variable-speed exhaust fan timers for use with compatible ceiling fans as well as triple combination switches to control multiple devices.
