All-in-one compressor units: what to check before installing in a small workshop
Before installing an all-in-one compressor, check floor space, ventilation, power supply, condensate and noise. Keli-Parts KLI-IT: 7.5-22 kW, ready to run.
An all-in-one screw compressor — receiver, dryer and filtration built into one package — looks like a straightforward way to put clean, dry air into a small workshop, and often it is. What it removes is the piping project, not the planning work. A short checklist before installation saves the callbacks that come from skipping it.
What the integrated package replaces
A conventional setup pairs the compressor with a separate receiver, a dryer and filters, joined by piping someone fabricates on site. An all-in-one unit builds those components into a single frame, so site work shrinks to the connections. Keli's KLI-IT series covers 7.5-22 kW in this format, and the promise on the product page is direct: connect power and air lines and it runs.
The gain is real for small workshops: no separate tank and dryer to mount, fewer joints to leak, one machine to service instead of three. The trade-off is that whatever the building does around the cabinet — heat, dust, moisture — now reaches every function at once, which is why the checks below are worth an hour.
Floor space and ventilation
Measure the footprint, then add clearance for airflow and service access. An integrated unit packs a compressor, dryer and tank into one volume, and all of it rejects heat; a cabinet pushed into a corner with stagnant air makes the dryer fight hot inlet air and the compressor fight a hot room.
Ventilation is the check small workshops skip too often. The room needs a path for cool air in and hot air out; if the unit must sit in an enclosed space, plan a fan or duct before installation day, not after the first shutdown on a hot afternoon.
Power supply, confirmed before ordering
Check what the building can actually deliver: voltage, phase and breaker capacity for the model being quoted. This is one of the three inputs Keli asks for on complete-unit inquiries — alongside air consumption and working pressure — because a unit specified for the wrong supply becomes an expensive return shipment. Confirm the cable route and disconnect while the walls are still open. Shops that add machines later should also think about spare capacity at the panel, since the next unit will share the same supply.
Condensate drainage
The dryer and the receiver both collect condensate, and an integrated unit concentrates that water at one point. Decide where it goes: a drain line to a suitable disposal point, with any automatic drains left connected and functioning — not plugged temporarily during installation, a habit that resurfaces later as wet air at the point of use.
In cold buildings, remember that drains and lines can freeze in winter, and route the condensate so it cannot pool under the unit and keep the floor wet.
Noise and placement
Placement decides how much the machine room and the workshop hear each other. Put the unit against a wall away from quiet work, keep the inlet side clear, and leave access space for the items that will need changing each service interval — filters, separator, oil. In a small building, decide placement before ordering rather than improvising around a fixed pipe stub. If the workshop shares a building with an office or a neighbor, it is cheaper to agree on placement now than to build an enclosure after complaints.
Sizing and ordering: what Keli needs from you
Size the unit on measured demand, not on the largest tool in the shop: air consumption in m3/min, the working pressure the process needs, and the site power supply. Oversizing costs money up front and pushes the machine into low-load running; undersizing shows up as pressure drops during peak shifts.
Keli quotes the KLI-IT all-in-one range from 7.5 to 22 kW against those three inputs, typically within one working day, with packing information included. Units ship with Keli's own air filter, oil filter, separator and service kit installed, under a 12-month warranty, so the first service cycle is already covered.
