From Distribution Line to Air Tool
A Drop Station Is More Than an Air Outlet
The main compressed air piping system moves air throughout a garage, shop or facility. A drop station finishes that distribution system by bringing compressed air to the workstation and preparing it for the equipment that actually uses it.
A well-planned drop should provide adequate airflow and pressure, convenient tool access, organized hose storage and appropriate point-of-use air preparation. It should also be positioned so the station can be serviced or expanded without unnecessarily reworking the main piping system.
Before You Design the Drop
Do You Need the AIRpipe Distribution System or Just the Workstation?
These are two related but different parts of the compressed air system. If you are starting from the compressor, build or size the AIRpipe distribution network first. If AIRpipe already reaches the work area, you can go directly to designing the individual drop station.
Starting From Scratch
Build the AIRpipe Distribution System First
The distribution system carries compressed air from the compressor to one or more outlet locations around the garage or shop.
- Determine how many work areas need compressed air.
- Plan the main line and branch layout.
- Size the piping for system airflow and distance.
- Create the outlet stations where the work happens.
AIRpipe Already Installed
Finish the Individual Drop Station
If compressed air already reaches the workstation, design the point-of-use equipment around the tools and work performed there.
- Confirm required CFM and PSI.
- Choose drop placement and hose reach.
- Select the regulator or FRL configuration.
- Choose the reel, hose, manifold and fittings.
The Complete Path
Where the Drop Station Fits in Your AIRpipe System
Think of the drop station as the final section of the compressed air distribution system. The main line supplies the air; the drop station delivers it in a usable form at the workstation.

Planning Tip: Size and design the main distribution system first. For garage installations, the AIRpipe Garage Kits provide preconfigured 1-, 3-, 4- and 5-station distribution layouts. Once the outlet locations are established, design each drop around the airflow, pressure and reach required at that workstation.
Step-by-Step
How to Plan an AIRpipe Drop Station
Work from the application backward. Determine what the workstation needs before choosing the hose, fittings or final drop configuration.
1
Identify What the Drop Will Supply
Start with the tools, machines or processes that will use the station. A tire inflation station has very different airflow requirements from a workstation supplying an impact wrench, blast cabinet or multiple pneumatic tools.
- List every tool or machine connected to the station.
- Record the required operating PSI.
- Record the required CFM or SCFM.
- Determine whether multiple tools may operate simultaneously.
- Consider equipment you may add later.
Design for demand, not just the connection size. A large fitting does not correct an undersized hose, restricted regulator or insufficient upstream airflow.
2
Choose the Drop Location
Place the station where the work actually happens. Good placement reduces unnecessary hose length, keeps hoses away from traffic areas and makes tools easier to reach.
- Locate drops near permanent workstations or equipment.
- Consider the full working radius of the hose.
- Avoid creating hose paths across walkways when possible.
- Keep valves, regulators and service components accessible.
- Plan additional drops for future work areas.
3
Determine the Required Airflow
Every component between the main line and the tool can affect airflow. The drop, valve, regulator, manifold, fittings, hose and couplers should all support the demand of the connected equipment.
- Use the highest realistic simultaneous workstation demand.
- Avoid unnecessarily restrictive fittings or regulators.
- Account for hose length when selecting hose diameter.
- Consider peak demand rather than average consumption alone.

4
Select the Hose Diameter and Length
The hose is the final air pathway before the tool and can become a restriction when it is too small or unnecessarily long. Select hose diameter based on tool airflow demand, operating pressure and required reach.
- Use only as much hose length as the workstation needs.
- Higher-flow tools may require larger-diameter hose.
- Long hose runs increase resistance and pressure loss.
- Match hose pressure rating to the compressed air system.
5
Choose the Hose Reel and Mounting Position
A hose reel keeps the work area organized and gives the operator controlled reach from the drop station. Reel location should support the work area without requiring excessive hose length.
- Wall mounting works well beside fixed workstations.
- Ceiling mounting can keep hoses above work and traffic areas.
- Consider the reel's hose diameter and flow capacity.
- Make sure the reel can reach the entire intended work zone.
- Allow access for inspection and maintenance.
6
Determine Point-of-Use Air Preparation
Some workstations only need regulated compressed air, while others may require additional filtration or lubrication. Match point-of-use treatment to the equipment manufacturer's requirements and the quality of air already supplied by the main system.
- Use a regulator when the tool requires lower controlled pressure.
- Add filtration where contaminants could affect equipment or processes.
- Use lubrication only when the downstream equipment requires it.
- Do not assume every workstation requires the same FRL configuration.

7
Choose Fittings, Couplers and Manifolds
The final connections should support both airflow and how the station will be used. A single-tool workstation may only need one outlet, while a service bay or fabrication area may benefit from a manifold with several connection points.
- Use compatible plug and coupler profiles.
- Consider high-flow fittings for higher-demand tools.
- Use a manifold when multiple outlets are needed.
- Avoid unnecessary reducers that create restrictions.
8
Plan for Isolation and Future Expansion
A modular compressed air system should be designed with future changes in mind. Isolation points make maintenance easier, while additional tees, branches or planned connection points can simplify future expansion.
- Provide a shutoff point for the workstation.
- Leave reasonable access to fittings and connections.
- Consider where another drop could be added later.
- Plan for future equipment with greater airflow demand.

Component Checklist
What Goes Into an AIRpipe Drop Station?
Not every station needs every component, but these are the primary pieces to consider when building a complete point-of-use connection.
| Component | Purpose | What to Consider |
|---|---|---|
| AIRpipe Drop | Routes air from the main distribution line to the workstation. | Location, pipe size, airflow demand and future expansion. |
| Shutoff Valve | Allows the workstation to be isolated. | Accessibility and flow capacity. |
| Filter | Removes contaminants before air reaches equipment. | Air-quality requirement, flow and pressure drop. |
| Regulator | Controls downstream pressure. | Required tool PSI and regulator flow capacity. |
| Lubricator | Adds lubricant for equipment that requires lubricated air. | Only use where appropriate for the application. |
| Manifold | Provides multiple outlets from one station. | Number of ports, inlet size and simultaneous demand. |
| Hose Reel | Stores hose and provides controlled workstation reach. | Mounting position, hose length, diameter and duty level. |
| Air Hose | Connects the station to the tool or equipment. | Diameter, length, PSI rating, flexibility and environment. |
| Couplers & Fittings | Provide removable connections between components. | Profile compatibility, port size and flow capacity. |
Need Several Drop Locations?
Build the Distribution Side With an AIRpipe Garage Kit
For garage and Pro-Am applications, preconfigured AIRpipe Garage Kits create 1, 3, 4 or 5 outlet stations. Once those locations are established, apply this design process to complete each individual workstation.
Design by Application

Before You Build
AIRpipe Drop Station Planning Checklist
Before ordering components, confirm the requirements of the workstation and how it connects to the larger compressed air distribution system.
- Tools and equipment identified
- Required PSI confirmed
- Required CFM confirmed
- Simultaneous tool demand considered
- Drop location selected
- Hose work radius measured
- Hose diameter selected
- Reel mounting location selected
- Filtration/regulation requirements identified
- Fitting and coupler style selected

Already Have Existing Piping?
An AIRpipe drop or expansion does not necessarily require replacing the entire compressed air distribution system. Transition requirements depend on the existing piping, dimensions, fittings and operating conditions.
Build From the Main Line Out
Ready to Build Your AIRpipe System or Finish the Drop?
If you still need the distribution system, start with an AIRpipe Garage Kit or size the piping around your facility. If AIRpipe is already at the workstation, complete the drop with the isolation, air preparation, manifold, reel, hose and fittings required by the tools you actually use.
