2 Description
Oil vapour, is oil in a gaseous form and will pass straight through coalescing filters, which are designed to remove liquid oil and oil aerosols.
The OVR uses a large bed of activated carbon adsorbent, for the removal of oil vapour and odours and provides the ultimate protection against oil
contamination in all kinds of industries, where air purity is critical. The OVR must be protected by coalescing filters upstream of the unit.

It is assumed inlet oil vapour concentration does not exceed 0.05mg/m3 at 35°C (95°F).
For applications with higher oil vapour concentrations, please contact Parker domnick hunter for accurate sizing.
Filter Selection - Grade OVR
To correctly select an OVR oil vapour removal filter, the flow rate of the OVR must be adjusted for the minimum operating pressure,
maximum operational temperature and pressure dewpoint of the system.
3 Obtain the minimum operating pressure, maximum inlet temperature, maximum compressed air flow rate and dewpoint of the
compressed air at the inlet of the OVR.
4 Select correction factor for maximum inlet temperature from the CFT table to compressor type (always round up e.g. for 37°C use
40°C correction factor).
5 Select correction factor for minimum inlet pressure from the CFP (always round down e.g. for 5.3 bar use 5 bar correction factor).
6 Select correction factor for pressure dewpoint from the CFD table.
7 Calculate minimum filtration capacity.
Minimum filtration Capacity = Compressed Air Flow x CFT x CFP x CFD
8 Using the minimum filtration capacity, select an OVR model from the flow rate tables above (OVR selected must have a flow rate
equal to or greater than the minimum filtration capacity).
If the minimum filtration capacity exceeds the maximum values of the models shown within the tables, please contact Parker
domnick hunter for advice regarding larger multi-banked units.

2.3 Receiving and Inspecting the Equipment
The equipment is supplied in a sturdy wooden crate designed to be moved using a forklift truck or pallet truck. Refer to the technical specification
for packed weights and dimensions. On delivery of the equipment check the crate and its contents for damage, If there are any signs of damage
to the crate, or there are any parts missing please inform the delivery company immediately and contact your local Parker domnick hunter office.
2.3.1 Storage
The equipment should be stored, within the packing crate, in a clean dry environment. If the crate is stored in an area where the environmental
conditions fall outside of those specified in the technical specification, it should be moved to its final location (installation site) and left to stabilise
prior to unpacking. Failure to do this could cause condensing humidity and potential failure of the equipment.
2.3.2 Unpacking
Remove the lid and all four sides of the packing crate (A) and unscrew the 4 nuts that secure the unit to the base of the crate (B). Lift the unit
using suitable slings and an overhead crane (C).
Carefully move the unit to its final location, using a forklift truck or pallet truck.

3 Installation and Commissioning
3.1 Recommended System Layout
OVR is an oil vapour removal filter and requires the prior reduction of liquid oil and oil aerosols to function correctly.
Coalescing filters must be installed upstream of the OVR unit (fig 1) to reduce aerosols. These filters do not need to be directly in front of the
OVR, they can be part of a purification package in the compressor room. OVR must be protected with Parker domnick hunter OIL-X EVOLUTION
Grade AO & AA coalescing filters to achieve claimed air purity specification.
OVR can be installed either in the compressor room or at point of use. Should an installation have old, contaminated piping, an OVR may be
required in both the compressor room (to protect the piping system) and at the point of use (to remove vapour from the piping system) to achieve
desired air purity (fig 2).
OVR uses granular activated carbon for the reduction of oil vapour. For optimum performance, the compressed air should be dry (OVR installed
downstream of a refrigeration or adsorption dryer) (fig 1 & 2). Should the installation dictate the use of the OVR prior to the dryer, the OVR must
be sized correctly for high moisture content of the air and must always be installed downstream of the coalescing filters (fig 3) i.e. the last filter
stage between the coalescing filters and the dryer. Coalescing filters should be protected from liquid oil / water. Should the coalescing filters be
installed in a place where liquids are present, a WS grade Water Separator must also be installed prior to the coalescing filters
Key:
Only competent personnel trained, qualified, and approved by Parker domnick hunter should perform installation,
commissioning, service and repair procedures.
