Principle of operation

Monnier lubricators are used to maintain the proper ratio of oil

and air and to maximize the performance and guarantee long life

of pneumatic machinery.

Once the oil rate has been set, a Monnier lubricator provides

reliable automatic lubrication. The Monnier design ensures efficient

and dependable performance.

The Monnier Venturi valve (1) automatically maintains the ratio of

oil to air that the user selects. It assures lubrication even at the

lowest possible air flow (see Capacities on page 2). By

automatically increasing the air pressure behind the oil in the

main reservoir (2) in proportion to the increased air flow, the

Venturi valve provides the desired degree of lubrication

regardless of air flowrate.

The Monnier sight dome (3) is moulded from transparent

polycarbonate that can be viewed at a full 360°. It includes an

adjustment screw (4) for setting the oil rate, and a sight-feed

tube (5) where the oil can be visually measured, drop by drop.

As standard, each lubricator is supplied with a " diameter

tamper-proof ball (6) that may be pressed or tapped into the top

of the sight dome adjustment area after the oil rate has been set.

This prevents any further adjustment by unauthorized personnel.

The automatic air control valve allows you to fill the oil reservoir

(2) while the unit is pressurised and without shutting down.

Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions

(IM-P504-16) supplied with the product.

Warning:

Polycarbonate bowls are attacked by phosphate ester fluids, paint

thinners and carbon tetrachloride. These and similar substances

should never be allowed to come into contact with the bowl. Certain

compressor lubricating oils also contain additives harmful to

polycarbonate and, where there is any doubt, we recommend, in

the interest of safety that a metal bowl or bowl guard be fitted.

Lubricant:

The oil used must be compatible with the equipment being served

by the lubricator and with the materials of construction of the

lubricator itself. Generally the oil will be of the free fogging type in

the viscosity rang of 7.5 to 64 centistokes (45 to 280 seconds

Redwood No. 1) at 38°F.

Installation note:

Fit into a horizontal pipeline with the air flow in the direction of the

arrow and bowl vertically downwards. The lubricator should be

fitted as close as possible to the unit it is serving. A Monnier

international filter (MF2M) should be fitted upstream to prevent

any contaminants reaching the system to be lubricated.

How to order

Example: 1 off IL1M Monnier international compressed air

lubricator having a female 1⁄2" screwed BSP (BS 21 - Rp)

connection.

Note 1: The product will be supplied with a polycarbonate bowl

as standard. If a metal bowl is required (with or without sight level)

it must be clearly specified on the order.

Note 2: If any optional extras are required, they must be clearly

specified on the order.
