VACUU-LAN local vacuum networks are a lab-by-lab approach to scientific vacuum systems that saves energy, bench space and maintenance. A single under-bench pump can support the whole lab. These modular vacuum networks are located entirely within each lab, and replace central lab vacuum systems (CVS) and individual vacuum pumps in new labs or renovations.
What's the appeal? 70-90 percent energy savings vs. CVS; Adaptable as needs change; Huge water savings vs. aspirators; Reduced water and air pollution; Better vacuum quality than CVS; Fast, simple installation; No inter-lab cross-contamination like CVS; Suited for renovations and new construction; Right-sized installation for sustainability; Proven worldwide for over 20 years. Call the manufacturer for specification and design assistance.
VACUUBRAND takes great pride in its history of environmentally sensitive operations, and was the first company in the vacuum industry to earn ISO 14001 certification.

Prepare cabinets, benchtops, fume hoods and ceiling tiles using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
C.
Commencement of installation constitutes acceptance of conditions.
3.2
INSTALLATION
A.
Install in accordance with manufacturer's written instructions and recommendations. Prevent oil or grease from being introduced into tubing. Do not install components that have become contaminated internally.
B.
Vacuum network tubing shall be of PTFE of appropriate diameter and finish, as supplied by the vacuum network manufacturer. Tubing connections shall consist of compression fittings, with connections tested with a vacuum gauge of sufficient resolution to determine that the completed network conforms to manufacturer's specifications for effective vacuum pressures.
C.

D.
Locate equipment with adequate space for service, air circulation, tubing bends and access to condensate catchpots for routine operation. Provide no less than minimum as recommended by manufacturer.
E.
Pumps may be contained within cabinets but only with manufacturer-approved provisions made for adequate air circulation to ensure that ambient operating temperatures do not exceed 104 degrees F (40 degrees C). Periodically confirm that operating temperatures are within manufacturer recommended limits in the course of network operation to avoid invalidation of warranty.
F.
Pre-drill casework at casework manufacturer's factory to the greatest extent possible. Bench penetrations shall be in accordance with system design, and shall conform to component manufacturer's drilling templates.

Pre-punch/drill fume hood penetrations at fume hood manufacturer's factory to the greatest extent possible. Penetrations shall be in accordance with system design, and shall conform to component manufacturer's drilling templates.
H.
Tubing shall be free of dips and loops that could trap condensate. Where such low points are unavoidable an access fitting (T-connector) or drip leg and blind fitting shall be installed to provide means of removing collected condensate that is not removable with blow-through techniques.
I.
Vacuum exhausts from multiple pumps within the same room shall be connected individually to fume hood exhaust lines to minimize backpressure.
J.
Minimum Turn Radius for PTFE Tubing:
1.
Without Compression Fittings: 8 inches (200 mm).

Such test shall be conducted by turning on network server pump, and testing vacuum at the pump and at the most distant valve from the pump on the vacuum network with a gauge of 1 mbar resolution to confirm vacuum pressure at pump and throughout network are consistent with product specification.
E.
Installer shall perform initial vacuum tests using a procedure recommended by the manufacturer before third party system verification if such verification is required by Owner.
F.
Do not use water or air pressure to test system integrity.
