3/8 NPT polycarbonate piggyback filter regulator combines an air filter and regulator in one 3/8 inch national pipe thread unit, which saves manifold space and simplifies plumbing on air lines. The 5 ounce polycarbonate bowl with metal bowl guard holds contaminants and moisture while shielding the bowl, which supports visibility and durability in typical shop environments. A 40 micron filter screens out moderate-size particles from the air stream, which helps protect downstream tools and valves from wear in everyday compressed air use. The maximum pressure rating of 150 pounds per square inch allows the unit to serve many general air system applications, while the 50 standard cubic feet per minute flow capacity supports typical single-station and small manifold air demands.
The 3/8 inch national pipe thread connections tie directly into 3/8 NPT air circuits, which fits many mid-size hose and manifold layouts. The maximum 50 standard cubic feet per minute rating indicates the air volume the unit can handle, which helps match the regulator to expected consumption on individual drops. An automatic overnight drain clears accumulated moisture from the bowl, which reduces manual draining steps after shutdown periods. The operating temperature range of 40 degrees Fahrenheit to 125 degrees Fahrenheit defines the ambient range where the unit is intended to function, which aligns with many indoor shop and light industrial environments.
The Milton Industries 3/8 inch NPT piggyback duo is suited to air line components where a filter and regulator are required in one footprint, which is useful at individual workstations. The 150 pounds per square inch maximum pressure rating allows use on many shop air mains that operate within that limit, which supports consistent delivery to downstream devices. The 50 standard cubic feet per minute capacity fits typical air consumption for common tools connected through 3/8 inch plumbing, which helps maintain performance without oversizing the regulator. The 5 ounce bowl capacity offers room for collected condensate between drain cycles, which supports day-to-day operation without frequent interruptions.
The automatic overnight drain feature discharges bowl moisture during idle periods, which helps keep water from carrying downstream at start-up. The relieving regulator design manages downstream pressure by venting excess, which gives more predictable response when reducing pressure for different tools or tasks. The three position knob that locks, adjusts, or removes provides clear tactile positions, which assists in holding a chosen pressure setting or changing settings when process requirements change. The non rising adjustment keeps the knob profile stable during use, which matters in tight installations or behind guards where clearance over the regulator body is limited. The 40 micron filter level balances airflow with practical filtration, which supports steady tool performance without excessive restriction under typical shop loads.
The 1110-5 Milton Industries unit is a 3/8 inch NPT piggyback filter regulator, which combines air filtration and pressure regulation in one body for use in air line components.
The piggyback filter regulator is rated for a maximum of 50 standard cubic feet per minute, which aligns with many single-station and small manifold compressed air applications.
This filter regulator has a maximum pressure rating of 150 pounds per square inch, which allows use on many general shop air systems designed within that limit.
The automatic overnight drain releases bowl moisture during idle periods, which reduces retained water in the bowl and helps limit moisture carryover into downstream air lines.
The 40 micron filter rating means the unit captures particles around that size, which supports general-purpose cleaning of compressed air ahead of downstream tools and components.
The three position knob allows locking, adjusting, or removing the adjustment control, which helps maintain set pressure or change it in a controlled way during air line setup.
The Milton Industries 3/8 inch NPT piggyback filter regulator with 5 ounce polycarbonate bowl, metal bowl guard, and 40 micron filter provides combined filtration and pressure control for air lines. The 150 pounds per square inch pressure rating, 50 standard cubic feet per minute capacity, automatic overnight drain, relieving regulator function, and three position non rising adjustment knob define how it will perform in service. When a single compact body handling both filtering and regulation at 3/8 inch national pipe thread is needed, this unit offers those specific characteristics for air line components.
