Introduction
The Precision Air Compressor is designed to complement the Precision modular series
of gas s, providing clean, dry, oil-free compressed air, while fitting neatly into any lab
space.
Other features include:
• Suitable to supply compressed air for Precision Nitrogen, Nitrogen Trace and Zero
Air systems as well as Peak Scientific TOC models.
• Generates compressed air on demand.
• Minimum maintenance with only a compressor service and filter change per annum.
• Small and Stackable.
With the Precision Air Compressor based on proven technology, it provides a source of
dry, clean and oil-free compressed air.
To ensure this air compressor model meets our high expectations with regards
to reliability and performance, we have tested this new model extensively at our
manufacturing plant and with end users around the world to ensure reliability and
longevity of the system.

Unpacking
Although Peak Scientific takes every precaution with safe transit and packaging, it is
advisable to fully inspect the unit for any sign of transit damage.
Check ‘SHOCKWATCH’ and ‘TIP-N-TELL’ labels for signs of rough handling prior to
unpacking.

Any damage should be reported immediately to the carrier and Peak Scientific or the
Peak Partner from where the unit was purchased.
Follow the unpacking instructions posted on the side of the crate. It will require
two people to remove the unit from the shipping crate and to manoeuvre the air
compressor onto the bench.
Please save the product packaging for storage or future shipment of the air compressor.
Note: Included with the air compressor is a “Fittings Kit” containing mains power leads
for UK, EU & US and also all the required fittings and warranty registration card. Be
careful not to discard these with the packaging. 

Page 10

Fittings Kit Contents
Supplied in the Fittings Kit are all the fittings required to connect the air compressor to
the application. The contents of the Fittings Kit are as follows:
1. Teflon Tubing x 3m
2. ¼” Compression Fitting x 2
3. ¼” Tee Compression Fitting

x1

4. 2.5mm Hex Key x 1
5. UK Mains Power Cable x 1
6. EU Mains Power Cable x 1
7. US Mains Power Cable 110v

x1

8. US Mains Power Cable 230v

x1

All of the air compressor output ports are located on the output panel at the rear of the
unit.

Unpacking Instructions
The unit weight constitutes a two person lift and as such, safe lifting practices should
be employed; do not attempt to lift on your own, as you will significantly increase the
chance of injury & damage to yourself and others around you.
1. Remove the screws encircled in red around the bottom of the crate lid and lift
upwards.
2. Next, with someone on either side of the unit, position your hands underneath the
unit ready to lift.
3. Ensuring your knees are bent and your back is straight, lift the unit to the desired
location.

Page 11

Installation
Compressor Environment
The air compressor is designed for indoor use only. Storing of corrosive substances near
the air compressor is not recommended. Saline salt spillages around the air compressor
should be cleaned up immediately. It should be installed adjacent to the application(s)
it is supplying. If this is not convenient then the unit can be sited elsewhere, however,
consideration should be made of the lengths of pipe runs as pressure drops can result
from extended runs of pipe.
Performance of the air compressor (like all sophisticated equipment) is affected by
ambient conditions. Note should also be taken to the proximity of Air Conditioning
outlets. These can sometimes give rise to “pockets” of air with high relative humidity.
Operation of the unit within such a pocket could adversely affect its performance.
Consideration should also be given to the air flow around the unit. It is recommended
that an air gap of 75mm (3”) should be maintained down both sides and at the rear of
the unit. Please refer to the drawing below for the general dimensions of the unit.
Minimum Operating Ambient Temperature:

5 °C (41 °F)

Maximum Operating Ambient Temperature:

35 °C (95 °F)

The air compressor must always be placed on a flat, level surface.
Failure to do so will affect the performance of the unit.

Electrical Connection
Connect the air compressor into an appropriate electricity supply, between 100-230VAC.
Refer to the air compressor serial plate for input specification and ensure your supply
matches the requirements.
If the appropriate power cord is not supplied; a new CSA, UL approved power cord,
rated to at least 10 amps, can be fitted by a qualified electrician.

WARNING

This unit is classified as SAFETY CLASS 1. THIS UNIT MUST BE
EARTHED. Before connecting the unit to the mains supply, please
check the information on the serial plate. The mains supply must be of
the stated AC voltage and frequency.

Electrical requirements are nominal +/- 10% depending on chosen model. Extended
periods at extremes can have a detrimental effect on the operation and life of the Air
Compressor.
If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment maybe impaired.
WARNING

Page 15

Connecting to the application
Once the initial purge run of 30 minutes has completed the compressor is now ready to
be connected to the application(s).
The pressure in the internal storage tanks must be allowed to dissipate
before connecting the compressor to the application(s)
CAUTION

Attach the ¼” compression fitting to the outlet of the air compressor. Using the ¼”
tubing supplied, connect the outlet of the air compressor to the inlet on the application.
If you require more tubing than is supplied please refer to the Tubing Lengths section.

CAUTION

Once the tubing is connected to the application, please ensure that it
is thoroughly checked for being leak-tight. Even the slightest leak in
the gas supply between the air compressor and the application can
lead to a reduction in efficiency.

Tubing Lengths

CAUTION



The diameter of the tubing which will be connected to the gas outlet is
important and is determined by the length of tubing required. Failure
to follow these recommendations could lead to excessive pressure
drop between the air compressor and its application


Use ¼”/3⁄16” (¼” O/D, 3⁄16” I/D) P.T.F.E. tubing.


> 10 - 40 meters: Use 3⁄8”/ 5⁄16” (3⁄8” O/D, 5⁄16” I/D). Tubing and fittings not supplied
in the fittings kit.

> 40 metres:


Please contact Peak Scientific with the relevant distance and
we will calculate the flow resistance and the tubing size required.

A combination of ¼”/3⁄16” and 3⁄8”/5⁄16” tubing may be used to ensure that there is no
large diameter tubing within the lab (i.e. for the first 20 meters from the air compressor
use 3⁄8”/5⁄16” and the final 10 meters to the application use ¼”/3⁄16” tubing). Keep the
connections and bends to a minimum.

Page 16

Normal Operation
The Precision Air Compressor is designed specifically to minimize operator
involvement. Given that the system is installed as described in earlier sections and is
serviced in accordance with the specified maintenance recommendations (see Service
Requirements), then it should simply be a matter of turning the air compressor on when
it is required.
The air compressor will automatically produce the factory set flow and pressure as
detailed in the Technical Specifications.

On Demand Gas
The air compressor system will produce compressed air on demand. If the application
is operating and requires a gas flow, the system it is connected to will supply this to
suit the requirements of the application. If the application requirement for gas stops,
the system will also stop, once it has reached its upper set limit in the internal storage
tanks. If the demand from the application starts again, the system will detect the
demand for gas and will automatically start again to suit the demand.

Unusual Operation
If at any time the air comrpessor begins to emit excessive noise or vibration, then it
should be switched off and you should contact Peak Scientific or the Peak Partner from
which the unit has been purchased.

Cleaning
Clean the outside of the unit only using warm soapy water and a clean damp cloth.
Ensure all excess fluid is thoroughly removed from the cloth prior to use.
Cleaning should only be undertaken with the power switched off and
the power cord removed from the rear of the air compressor.

CAUTION

Under no circumstances should any solvents or abrasive cleaning
solutions be used as these can contain fumes that could be harmful to
the air compressor. Chlorine-based bleach cleaning solutions should
not be used on the air compressor or within its operating environment.
Care should be taken with Leak Detections Liquids.

CAUTION
