Brink - Model CGF - Compressed Gas Filter
Submicron oil and water particles are present in gas streams following industrial compressors. These mist particles are formed by evaporation and condensation due to the heat of compression and from lubricant blow-by, if lubricated compressors are used. The water can accumulate in air lines and freeze in cold weather. The water and oil can damage downstream instruments, tools, airveying membranes and contaminate final product. If a desiccant dryer is used, the oil and water particles will over load and reduce the life of the desiccant.
The MECS Compressed Gas Filter (CGF) utilizes a combination of low operating velocities, deep beds, and Brownian diffusion as the predominant collecting mechanism to achieve high efficiency with very long operating life and low pressure drops. With the standard CGF, 99.5% of the submicron mists are removed. (Models are available to achieve 99.95+% removal). In typical compressed air service, CGF operates 10-15 years, which is much longer than replaceable coalescing filters. Pressure drop is typically less than 0.5 PSIG which provides appreciable operating power savings over coalescing filters. The CGF can also tolerate high inlet loadings caused by temporary upsets or surges.
How It Works:
The MECS Compressed Gas Filter consists of special glass fibers packed between screens or perforated plates. As the compressed air (or other gas)containing oil and water particles passes through the fiber bed filter, the particles collect on the fibers by impaction and Brownian diffusion. These particles agglomerate and form into liquid films which are moved to the outside surface of the filter by gas drag. Gravity moves the collected liquid down the filter and into the sump where it is drained off by a liquid trap or timed solenoids.
