1. General Information
DESCRIPTION OF THE MACHINE
The SILENT series comprises a range of reciprocating, single stage and dual stage compressors with
oil-
free or splash lubrication and vertical or “V” twin cylinders, for use in industrial applications. The
various models can be direct motor coupled or V belt driven by single-phase
electric motors with direct starting or three-phase motors with direct or delta-star starting. They have
independent forced ventilation, a control panel and operating parameters display. The main difference
between single and dual stage models consists in the way the air is compressed. In single stage
compressors, the air is sucked in and compressed once before being made available. In dual stage
compressors the air is compressed in two stages; first of all by the low pressure piston and then by a
piston with a smaller diameter (high pressure). In terms of performance, the difference between the two
types consists in their maximum operating pressure, which is 10 bar for single stage compressors and
11 or 13 bar for dual stage
compressors. In order to guarantee compliance with project quality and safety specifications pursuant to
ISO 9001 certification and European directives, all parts used to manufacture our compressors are
tested for thermal resistance and mechanical strength. These tests consist of exposing parts to
temperatures and mechanical stress values that exceed those encountered during normal operation.
Electric motors comply with all statutory requirements and have class F insulation.
Our compressors are suitable for:
•
Supplying painting plants
•
Handling lift trucks
•
Supplying assembly lines
•
Sandblasting
•
Supplying presses and pneumatic tools
Before use, make sure that the specific application requires an air capacity that does not exceed 60% of
the compressor’s capacity.
This is particularly important when supplying air to brake-clutch assemblies of mechanical presses, in
order to ensure the safety of operators and prevent possible malfunctioning of twin valves.
Noise emissions under pressure fall within the limits defined by Presidential Decree 81/08, and
operators are not therefore required to wear protective ear muffs.
CRITERIA FOR USE
Silenced compressors should NOT be activated CONTINUOUSLY but made to operate for approximately 60% of
running time. The user must take into consideration the requirements of the specific application (amount of air
needed, maximum pressure, total number of air outlets, continuity thereof), in order to define the most
appropriate method of use and define the capacity of the external sump in order to guarantee continuous delivery
while ensuring maximum efficiency. Examples of recommended sump capacities are:
1. 200 litres for the ZT500 model
2. 300 litres for the ZT750 - ZT850 models
3. 500 litres for the ZT850 - ZT1100 models
4. 1000 litres for the ZT1500 - ZT2200
– ZT2600 models
Compressors in the SILENT 1 series incorporate a 24 litre sump inside the cabinet and do not therefore require
the use of an external sump. If the user wishes to use an external sump in any case, a capacity of 100 litres is
recommended.
