Atlas Copco BD 100+

Atlas Copco BD 100+ is a desiccant blower-purge compressed-air dryer rated at 212 SCFM (100 l/s), delivering a -40°F pressure dew point at ISO 7183 Annex A2 conditions. Maximum inlet pressure: 210 PSI; minimum: 60 PSI. Electrical: 460V / 60 Hz / 3-phase, 4.5 kW. Weight: 1,450 lbs. Ambient temperature maximum: 122°F. Externally heated blower-purge regeneration using ambient air; dual-bed activated alumina and molecular sieve maintains stable dewpoint under load swings with only 2% purge loss — a major energy advantage over heatless designs at this flow rate. ELEKTRONIKON touchscreen controller included. Suitable for instrument air, pharmaceutical processes, and any application requiring sub-zero dewpoint with high flow. Price: approximately 8,900 (quote-only at most dealers). Note: model suffix denotes l/s free air delivery (BD 100+ = 100 l/s ≈ 212 SCFM).
