ROAD TO OIL-FREE Start Finish the oil-free medical world!

ROAD TO OIL-FREE Today Oil injected technology Which technologies can we offer? What is the difference with an industrial compressor? Finish the oil-free medical world! What are the specific features of each technology? What will be the price? How to order?

CLEAN AIR IS A MUST FOR PATIENT SAFETY Two ideologies: 1. HTM/ISO take in ambient air, use any type of air compression method (oil-injected or oilfree) and ensure patient safety by means of an ultra high purification system (MED + QDT) 2. NFPA99 (US) / CSA 7396-1 (CAN) be more stringent on air quality intake and ensure patient safety by not adding contaminants during the air compression stage In normal operation both systems will provide clean air, however only oil-free solutions fully eliminate the risk of oil carry-over to the patient

OIL-FREE, CONTAMINANT FREE RISK FREE WHAT'S WRONG WITH OIL IN AIR? 2-3 mg/m³ = 5 LITERS / YEAR

1)UNDER-USAGE A tangible threat in medical ISO7396-1 (HTM02-01 for UK) requires 3 redundant compressors The design flow is often hugely oversized! Emulsification The addition of terminal units in areas with low usage or occupancy adds a need for additional flow capacity which is seldom needed think of medical air in ward areas for example HOW OFTEN DO YOU SEE THESE IN USE? Sometimes? Often? Occasionally? ALMOST NEVER... All this under-usage leads to creation of condensation & blockages downstream. Solutions? Oil-free (or VSD)

1)UNDER-USAGE A tangible threat in medical Other applications vulnerable to under-usage: Teaching facilities Military facilities Laboratories or R&D facilities Sterilisation facilities Other causes of under-usage: Oversizing for future expansion of a hospital adds up to 25% on top of an already oversized system IF THE AIRPLANT IS SIGNIFICANTLY UNDER-USED OIL-FREE (OR VSD) ELIMINATES THE RISK!

2)OIL CARRY OVER A tangible threat in medical ISO7396-1 (HTM02-01 for UK) requires 2 redundant Air treatment devices (MED) Performance stated at 20 C! What happens in real life?

CONSEQUENCES OF OIL A failure of any of the air treatment components could cause: Risk to patient health Require complete rebuilding of hospital pipelines Damage to expensive equipment (e.g. anesthesia machine)

3) LACK OF MAINTENANCE Causing damage to dryer components Although oil carry-over happens in medical systems, generally this does not cause harm to patients More likely the problem is contamination of components Saturated filters are often the route cause! This is often a problem with maintenance (OR LACK OF)! In particular this is a problem where there is little or no dedication to preventive or routine maintenance.

3)LACK OF MAINTENANCE Causing damage to Air treatment components Does this sound familiar in your facility? If it does then oil-free solutions offer complete piece of mind By eliminating the risk of oil damaging the purification system = TOTAL PATIENT SAFETY

ATLAS COPCO IS A Global market Leader in oil-free technology Active in oil-free for more than 60 years We have installed > 40,000 oil-free machines World wide We are The First manufacturer to receive ISO 8573-1 CLASS 0 certificate We offer the widest range of pressures (up to 13 bar - AQ) and FAD (2 l/s - 155 l/s), using 3 different technologies to produce 100% oil-free air: piston - tooth - water injected screw

ENVIRONMENTAL FRIENDLY FACT The removal of waste oil is expensive, difficult to handle and an environmental hazard Local regulations oblige additional investments to remove and treat contaminated condensate.

CONCLUSION THE ADVANTAGES OF OIL-FREE AIRPLANTS No risk of oil carry-over No risk of damaged dryer components No emulsification More environmental friendly Higher customer value Clean air is a choice you make choose oil free Oil-free, contaminant free risk free
