3800H ROLAIR Automatic Tank Drain

Review ROLAIR Automatic Tank Drain

The Rolair 3800H Automatic Tank Drain is a versatile and efficient solution for maintaining optimal water levels in your heating system or hot water tank. Designed with advanced technology, this drain offers automatic operation, ensuring consistent performance and minimizing the need for manual intervention.

This drain features a heavy-duty, corrosion-resistant construction, making it suitable for use in harsh environments. The 3/4-inch NPT threaded connection ensures a secure fit with most standard heating system and hot water tank drains. The drain body is made of high-quality brass, while the impeller and float assembly are constructed of durable, impact-resistant plastic.

The Rolair 3800H Automatic Tank Drain operates through a simple yet effective float-operated mechanism. As water level rises, the float rises, which in turn activates the impeller, causing it to spin and pump out excess water. Once the water level drops, the float returns to its original position, and the impeller stops spinning. This continuous cycle ensures that your tank stays at the desired water level, preventing potential damage from overfilling.

One of the most significant advantages of the Rolair 3800H Automatic Tank Drain is its adjustable water level control. By adjusting the float, you can easily set the desired water level for your specific application. This feature offers greater flexibility and customization, ensuring optimal system performance.

Additionally, the Rolair 3800H Automatic Tank Drain comes with a conveniently located drain outlet, making it easy to connect to a drain line or bucket for disposal. The drain also includes a built-in air vent to prevent vacuum conditions and maintain proper air pressure within the system.

In conclusion, the Rolair 3800H Automatic Tank Drain is a top-performing, corrosion-resistant solution for maintaining optimal water levels in your heating system or hot water tank. Its automatic operation, adjustable water level control, and durable construction make it an essential tool for ensuring the longevity and efficiency of your system.
