About manifolds & air prep

Manifolds and Air Preparation components are essential for delivering conditioned compressed air to pneumatic systems. This category includes Filters, Regulators, and Lubricators (FRLs), often supplied as modular units or individual components. Filters remove particulates and moisture from the air supply, with common types including coalescing filters for oil removal and particulate filters rated by micron size (e.g., 5-micron, 40-micron). Regulators maintain a constant output pressure, typically specified by their operating pressure range (e.g., 0-125 psi, 0-10 bar) and port size (e.g., 1/4" NPT, G1/2). Lubricators inject a fine mist of oil into the air stream to lubricate downstream pneumatic components, with oil capacity and flow rate being key specifications. Distribution manifolds provide multiple output ports from a single input, simplifying pneumatic plumbing. Manifolds are specified by the number of stations, port sizes, and materials. Common materials for FRLs and manifolds include aluminum, zinc, and engineering plastics, with seals often made from NBR or FKM. Operating temperature range, maximum inlet pressure, and flow coefficient (Cv) are critical performance parameters for all components within this category.

How to choose

Selecting Manifolds & Air Prep components involves a sequential decision process. First, determine the required air quality: does the application need particulate filtration, oil removal, or both? This dictates filter type and micron rating. Second, establish the desired operating pressure for the pneumatic system; this defines the regulator's output range. Third, evaluate if lubrication is necessary for downstream components, considering the type of pneumatic devices. Fourth, specify the required flow rate (SCFM or Nm3/hr) and port sizes (e.g., NPT, G-thread) to ensure adequate air delivery and compatibility with existing plumbing. Finally, for distribution manifolds, determine the number of required output ports and their sizes, ensuring material compatibility with the environment and pressure requirements.
