The Air Dryer series from O'Keefe Controls has new models in their compressed air dryer catalog to meet low flow needs. The shoebox sized unit can be installed in tight spaces. The self-regenerative model offers high efficiency at flow rates from 0.5 to 6 scfm. The self-regenerative model can operate at a minimum inlet pressure of 80 psig. A selection of these units is available for many applications.

The ID series is a heatless desiccant air dryer. The ID series produces dry air with a low dew point and offers a range of flow rates from 100 to 975 l/min. The unit's compact design eliminates the need for an electric control board or heater. The ID series' built-in indicator makes checking the outlet dew point easy. This desiccant-based air dryer routes the compressed incoming gas or air through a chamber containing a desiccant, which naturally absorbs moisture.

The 311C series is a timed insert module that continuously removes water vapor from compressed air. It features a molecular sieve desiccant in two stainless steel tanks. Flow control valves, a timer, and a purge flow discharge are used to regulate the drying process. The nominal dew point is -50degF at maximum flow, and even lower when the flow rate is less than maximum. The 311C series is the most cost-effective, yet highly effective, type of air dryer for any business.

The ID series is a heatless desiccant air dryer with flow rates from 100 to 975 l/min. The device is compact and lightweight and lacks an electrical control board. A built-in indicator allows you to check the outlet dew point quickly. The ID series uses a desiccant material to absorb moisture. This material also acts as a barrier to humidity. When the air is sufficiently dried, the dew point is even lower than -50degF.

The ID series is an insert module that offers continuous water vapor removal. This unit has two stainless steel tanks. The two tanks are connected to a timer that sequences the air flow through the desiccant. The timer also controls the purge flow. The system has a low dew point. The ID series is an excellent choice for applications requiring low dew point and clean air. There are no electrical components in the 311C air dryer.

The 311C series air dryer is an insert module that removes water vapor from air. The unit has two stainless steel tanks that remove water vapor at a constant rate. The system has a timer that automatically cycles the inlet air through the desiccant tanks. The purge flow discharges a small quantity of purge flow. At maximum flow, the dryer achieves a pressure dew point of -50deg F or even lower.
