COBRA DH 2780–6280 A

Overview

Dry screw vacuum pumps COBRA DH 2780–6280 A are presented as a compact and intelligent plug&pump solution with integrated vacuum booster, an intuitive 7" color touch screen control panel and possible remote control via web server. The system is completely gas-tight and dry, with fewer wear parts, longer service intervals and high energy efficiency; the VacBoost energy saving module provides 60% less power consumption at ultimate pressure. High pumping speed enables fast pump‑down times, for example in industrial load lock applications. Pumping speed at 1 hPa: COBRA DH 2780 A 2250 m³/h, COBRA DH 4580 A 3512 m³/h and COBRA DH 6280 A 4652 m³/h. Pumping speed at 0.75 TORR: COBRA DH 2780 A 1324.1 ACFM, COBRA DH 4580 A 2066.8 ACFM and COBRA DH 6280 A 2737.7 ACFM. Ultimate pressure is 0.001 hPa (mbar) corresponding to 0.00075 Torr for each model. Nominal motor rating is 26 kW for each model, with nominal motor rating backing pump 18.5 kW and nominal motor rating vacuum booster 11.0 kW. Nominal motor speed backing pump is 4320 min⁻¹ for all models; nominal motor speed vacuum booster is 4500 min⁻¹ for COBRA DH 2780 A, 7500 min⁻¹ for COBRA DH 4580 A and 10500 min⁻¹ for COBRA DH 6280 A. Power consumption at ultimate pressure is 10 kW (COBRA DH 2780 A), 10.2 kW (COBRA DH 4580 A) and 10.4 kW (COBRA DH 6280 A), with idle mode consumption 4.6 kW for each model. Sound pressure level (ISO 2151), KpA = 3 dB is 69 dB(A). Water consumption (ISO 50 Hz) is 10 l/min and 14 l/min at 0.75 TORR / US 60 Hz.
