Working Principle and Construction
Working Principle
The air compressor starts after being plugged in and the power
inlet switch toggled. The power inlet switch is located above the
power inlet on the unit. Ambient room air is pulled in through the
airintakelterontheunit,pasttheheatexchangecoilandintothe
compressor. (Note: Excess moisture is directed to the water bottle
reservoir.) Here it is compressed, moves through the heat exchange
coil in order to reduce the air temperature, through an auto-draining
airlter,pressurereliefvalve,andpressureregulator.Theairthen
exits the unit and is delivered to the Precision Flow via the air hose.

Power Inlet Switch
The Vapotherm Q50 compressor makes use of a medical grade
power inlet switch. The power inlet switch contains two (2) fuses.
• 5ET 8-R (5mm X 20mm, 8A, SLOW BLOW, GLASS FUSE,
250V)
WARNING: To avoid risk of electric shock, this equipment
must only be connected to supply mains with
protective earth.
Air Intake
The compressor utilizes air from its surrounding environment. It
passes through multiple stages of ltration prior to delivery to the
PrecisionFlow.Therstltrationstageisaccessiblefromtheoutside
and should be cleaned once per week according to maintenance
procedures.Furtherltrationisaccessibleonlybytrainedpersonnel
during preventative maintenance.
WARNING: Never restrict or block the air intake. This could
result in failure to deliver therapy as intended.
Page 11

Air Outlet
The air exiting the Q50 compressor is to be used only in conjunction
with the Vapotherm Precision Flow system. The compressor output is
designed to match the performance needs of the Precision Flow up
to 40 L/min and as such has no user adjustable settings or gauges.
Air Exhaust
The air exhaust is located on the bottom of the unit and vents the
warm air used to cool the compressor.
WARNING: Do not block or restrict the air exhaust underneath
the compressor. This could result in failure to
deliver therapy as intended. When the unit is
placed on the oor, be sure that any ooring, such
as carpet, does not restrict the air exhaust.
WARNING: Do not remove the compressor feet. These are
designed to reduce noise and provide the required
space to allow the compressor to circulate su󰀩cient
cooling air throughout the system. Removal of the
feet could result in overheating of the system and
excessive noise.
WARNING: The bottom of the unit may become uncomfortably
warm if air ow is obstructed or under a single
fault condition. Do not lift the unit from the bottom
immediately after use.

Set-Up for Use
Mounting Positions
Thecompressorisintendedforuseintwocongurations,stand-alone
ontheoorormountedtoaPrecision Flow Roll Stand. If the Q50
Compressor is intended to be used stand-alone, no further work is
required: the compressor comes with four compressor feet to limit
noise and vibrations coming from the unit and holds the compressor
the correct distance from the oor to accommodate cooling air to
exhaust from the unit.
WARNING: Do not remove the compressor feet. These are
designed to reduce noise and provide the required
space to allow the compressor to circulate su󰀩cient
cooling air throughout the system. Removal of the
feet could result in overheating of the system and
excessive noise.
WARNING: Do not modify or alter the Q50 Compressor. Failure
to follow this warning may result in improper
operation, reduced life of the compressor, or failure
to deliver therapy.
Page 13

Pole Mount
The Q50 Compressor comes with the ability to be mounted onto the
Precision Flow Roll Stand via the pole mounts located on the side of
the compressor. When mounting to a Precision Flow Roll Stand, the
bottom of the compressor must be placed on the Precision Flow Roll
Stand base and no greater than 8” from the ground. The compressor
also must be placed over two locking casters of the Precision Flow
Roll Stand. Improper mounting the Q50 Compressor on the Precision
Flow Roll Stand will result in a higher risk of tipping the IV pole unit.
The Q50 compressor is only to be mounted on a Precision Flow Roll
Stand.
