  • SAFETY MESSAGES IN MANUAL AND IN WARNING LABELS Safety messages appearing in the manual and on warning labels utilize signal words that translate to a level of risk. Below are the definitions of the words used:

    WARNING: Indicates a hazardous situation that, if not avoided, could result in death or serious injury.

    CAUTION: Indicates a hazardous situation that, if not avoided, could result in minor or moderate injury.

    REMINDER : Indicates suggestions for proper use. Warning labels are attached to the air dryer. They look something like those below. Be sure that these labels are visible and in place. If they become damaged or illegible, contact SKF for replacement labels

    -WARNING- BEFORE SERVICING SFD DRYER UNIT(S) RELIEVE ALL AIR PRESSURE FROM DRYER UNIT(S) AND AIR LIN ES

    DO NOT OVER-TIGHTEN

    CARTRIDGE

    Lubri cate threads, O -rings & flat gasket with grease provided before installing cartridge Tighten cartridge ½ turn only after gasket contacts casting surface

  • SEPARATOR FILTER DRYER (SFD) Protect compressed air lines from oil, water and particulate The easy to maintain SFD is a compact heatless desiccant air dryer which delivers high quality compressed air capable of achieving superior pressure dew points -40°F or lower. Use the SFD when precision work requires high quality air. Reduce energy and operating costs with the SFD. Contaminated compressed air lines drags down productivity, raises operating costs, and increases maintenance requirements. SFD benefits include: • Requires less electrical usage than alternatives • Extends service life of pneumatic driven devices • Avoid expensive downtime to repair or replace equipment • Reduces prep time in spray applications • Eliminates rework due to compressed air contaminants • Modular design allows for quick, easy and flexible expansion

    Simple and easy to service: Maintenance personnel can easily spin off the desiccant cartridges and replace service components in a matter of minutes. Designed for outdoors - complies with NEMA 4 Standard - when equipped with thermostatically controlled heater package keeps dryer performing during winter months.
