Introduction

Foam Marker Description (Fig. 1)

The foam marker is an equipment used to
mark the area of ground that is being worked,
through foam. The foam is obtained mixing
the air with water and liquid foam solution.
The foam falls on the ground at regular
intervals and creates a demarcation line which
marks the area of the worked ground. The

foam marker can be xed onto all sprayers,

pneumatic and centrifugal manure distributors,
seeders and in general when precise working
is required. Fig.1 shows the equipment and its
components.

Liquid Foaming Agent Tank (Fig. 2)

The tank contains the solution created by
water and the foam solution (Fig.2-1). It
has a cap with safety valve which limits the
maximum pressure inside the tank at 0,75 bar
( Fig. 2-2).

Material of manufacture: polyethylene.

Compressor Block (Fig. 3)

It supplies the necessary pressure to the unit
to generate the foam bubbles. The group
includes the CM 40 membrane compressor
and electric valves: two for liquid and one
or two valves (relating to models) are for air
control.

Air-liquid Foam Diuser/ Mixer (Fig. 4)

The diuser mixes the compressed air with the

foaming liquid solution, creating foam bubble
which falls on the ground (Fig. 14). There are

two versions : the vertical foam diuser (Fig.1-

1,2,3 and 4) and the horizontal version (Fig.4-

5). Possible congurations for the vertical foam
diuser:

1. body only with bell: medium foam size

2. body with short diuser and conic

reduction : small foam size suitable

for turf/golf applications or oating on

vegetation

3. body only with short diuser: standard

foam size

4. body with short diuser and bell :

maximum foam size

Control Panel (Fig. 5)

It allows to select (Fig.5-1) the side from which
the foam bubble will exit. The feeding cable
(Fig. 5 -2) and the connection cable to the
compressor (Fig.5-3) are included.

Safety System (Fig. 6)

A safety valve has been installed on the tank
cap (Fig. 6 - 1) and it opens at a pressure
of 0,8 bar. This system is necessary in case
of hose obstruction, in order to avoid that
pressure rising inside the tank causes its
break. The tank cap has a safety stop (Fig.
6-2) to prevent its ejection, in case of opening
under pressure. Before removing the cap,
discharge the residual pressure by manually
operating the relief/safety valve (Fig. 6 – 1).

Avoid removing the cap before having
discharged every pressure residue in
the container.

Do not remove the cap safety stop.

Do not tamper with the safety valves.
