Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Pressure booster 2 | 214 Series P+ 2 Air Service Units UNLOCK LOCK General Warning It is recommended you follow the instructions below in order to prevent personal injury or damage to the booster. - The pressure booster is supplied as standard with the regulating spring completely unwand. in this condition it is possible to detect a leak of air from below the regulating knob or through the exhaust port. this conditions is standard for the unit. When the spring is completely unwand the downstream pressure and the inlet pressure are the same. in order to increase the downstream pressure it is necessary to operate th regulation knob increasing the sping compression. - Please apply the necessary safety measures to ensure that the booster only operates within the specified pressure range. Exceeding the maximum output pressure is dangerous. - The Booster is fitted with a non-return valve on the output which prevents discharge of the downstream pressure, It is recommended that a 3/2 valve be installed in the OUT connection if it is necessary to rapidly discharge the downstream pressure. - When the booster is not in use it is recommended that the inlet pressure is removed to let the booster stop, thus avoiding unexpected operation or malfunction. - If there is not downstream air consumption it is possible to register a leak through the exhaust port of the unit. this condition is normal and is the conseguence of the internal designed aimed at discharging any pressure building up in the unit in the rest condition. Use and maintenance The pressure booster must always be used in accordance with the operating parameters and instruction; any improper use may cause injury or malfunction. The pressure booster is not an alternative to a compressor because continuous uninterrupted operation will greatly reduce the life of the unit. - The operating life of the device depends mainly on the operational duty cycle. Prolonged uninterrupted use without pause may reduce the operating life of the booster. - Ensure the unit is supplied with a suitable compressed air supply, please note: appropriate filtration and lubrication may help to increase the durability of the product. - The input flow value must be equal or greater than double the output flow value (Q1/Q2>2). - Ensure that the value of the output pressure is at least 1bar higher than the input pressure (P2>P1+1). - To avoid pulsation of the output pressure during operation, it is recommended that an accumulation tank (reservoir) is installed in the downstream circuit. - Protect the booster exhaust ports from the ingress of dust or debris. - To reduce the noise generated by the unit, install silencers into the exhaust ports. - Pressure booster has an average life of about 20 millions of valve cycles, depending on working conditions (every back stroke corresponds to one valve cycles ). Regolazione della pressione The booster is fitted with an internal pressure regulator which allows regulation of the output pressure P2 and is also fitted with pressure relief valve. For correct operation of the booster, please consider the following instructions: - Air leaking from under the adjusting knob when the spring is decompressed is not a defect but a sign that the device is working correctly. - In order to increase the regulated pressure, pull the knob upwards to unlock, then rotate the knob in the direction indicated by the arrow (+). - To lock the knob after the adjustment has been made, push the knob downwards until it detents in the locked position. - To reduce the output pressure, pull the knob upwards, rotate the knob indicated by the arrow (-), the built in pressure relief valve will discharge the excess pressure from under the adjusting knob. - Always regulate the rising pressure.
