13.2 HIGH AIR PRESSURE SWITCH – APP086
HIGH AIR/GAS PRESSURE SWITCHES
PART NO: 98524/1025, 1049, 1094, 1095, 1096, 1102, 1103, 1104, 1107, 1128, 1135,
1136, 1137, 1210 & 1212
OPERATION - MANUAL START/AUTO STOP
Located as close as possible to the delivery, inlet air/gas line, the pressure switch stops the compressor
when the air/gas pressure rises or falls above or below the pre-set pressure setting.
TYPICAL SETTINGS - Set to actual operating pressures or check contract for details.
Set pressures: 98524/1025
Setting Range 30"hg vac - 15 psig rising
98524/1094
Setting Range 0.14 - 4 psig rising
98524/1095

98524/1096
Setting Range 1.4 - 28 psig rising
98524/1102

Reset Differential 0.6 bar
98524/1107
Setting range 0.2 - 4 bar g rising
Reset Differential 0.6 bar
98524/1128

98524/1135
Setting Range 0.2 - 4 bar g rising
Reset Differential 0.07 bar
98524/1136
Setting Range 3 - 70 bar g rising.
98524/1137
Setting Range 3 - 66.5 bar g rising.
98524/1210
Setting Range 5 – 40 mbar
98524/1212
Setting Range 70mbar – 70bar
The switch transforms a change of pressure into an electrical "On" or "Off" signal.
When a pre-set pressure is reached the snap action contact stops the compressor.
OPERATION - AUTO START/STOP
Located as close as possible to the delivery air/gas line, the pressure switch stops the compressor when the
upper pre-set pressure setting is attained and triggers off the start when the lower differential pressure limit
is reached.
TYPICAL SETTINGS - Set to actual operating pressures or check contract for details.
Set pressures: 98524/1049
Setting Range 2 - 42 bar g rising
Set Pressure HIGH 31 bar g rising
Set Pressure LOW 28 bar g falling.
98524/1104
Setting Range 2 - 70 bar g rising
Set Pressure HIGH 40 bar g rising
Set Pressure LOW 36 bar g falling.
98524/1137
Setting Range 3 - 66.5 bar g rising
Set Pressure HIGH 42 bar g rising
Set Pressure LOW 39 bar g falling.
The switch transforms a change of pressure into an electrical "On" or "Off" signal.
When a pre-set high pressure is reached the snap action contact stops the compressor, after dropping to
the lower setting, the compressor restarts.
