Frequently Asked Questions
What airflow does the RV 4000 offer?
See "Airflow" in the technical table: typically 1,000-5,000 m³/h for workshop use.
Airflow determines the number of machines that can be connected simultaneously. For centralized systems with multiple workstations, size with a 30% margin.
What hose diameter does it require?
See "Connection diameter" in the table: typically Ø100, Ø120 or Ø150 mm.
Larger diameters reduce pressure losses and improve efficiency. For systems with long runs (over 10 m), prefer Ø150 mm.
Bag/container capacity?
See "Container capacity" in the technical table: typically 70-300 liters.
Bags should be emptied before they become saturated to maintain suction flow. Models with large bags reduce intervention frequency.
Fine dust filtration?
Professional models offer fine filtration with class M or H for respirable dusts.
For treated wood and MDF panels, class M or higher is recommended. Krollit provides original replacement filters.
What is its power consumption?
See "Motor power" in the technical table: typically 1-7 kW.
Models above 3 kW require 400 V three-phase. Check availability in the workshop.
