REBUILDING FUME HOODS

EXTEND THE LIFE OF YOUR FUME HOOD SASH SYSTEM BY 15 TO 20 YEARS

Compare the cost of replacing a large fume hood with multiple sashes – with the cost of simply replacing the worn-out sash components.

Complete and competent replacement of the following items:

  1. Cables or Chains
  2. Pulleys or Sprockets
  3. Sashes or Sash glass
  4. Counter weights
  5. Bearings
  6. St.St. sash guide components
  7. Extension slides

Relieve ergonomic issues that are adversely affecting your research personnel.

  1. Most hoods can be brought within the industry standard 8 to 12 lbs. maximum force required to open or shut a sash.

Our technicians have already performed major rebuilds on hoods produced by all major US manufacturers. The specific team which rebuilds your hoods will have over 30 years experience in this custom field of operation.

Our technicians can also make modifications to existing systems which will aid you in your day to day research needs. Some of these unique hood changes might include, manifolds, stench boxes, distillation sections, distillation racks and shelving systems.

CONVERT YOUR VERTICAL SASH HOOD TO HORIZONTAL SASH

In certain instances the need for Horizontal sash systems outweighs the features of Vertical sash systems. In this case we can convert your Vertical sash hood to Horizontal sash. A special meeting will be needed to detail the changes to your hood.

PMP— PREVENTATIVE MAINTENANCE PROGRAM

Have you ever wondered if a preventative maintenance program on your
fume hoods could deter costly shut downs and major replacement costs for
your fume hood investment?

LF Systems Corp. has been doing these types of maintenance programs for years

Typical program for cable driven fume hoods:

  1. Open and close force analysis of current sash system
  2. Vacuuming and cleaning top of fume hood
  3. Removal of all miscellaneous debris
  4. Cleaning pulleys with special solvent and purging with pressurized air
  5. Lubrication of pulleys and cables with custom synthetic oil
  6. Lubrication of all extension slides – if part of the guide system
  7. Adjustment of sashes and weights for proper movement and alignment
  8. Recommendations will be made as to replacement parts if necessary

Typical program for chain driven fume hoods:

  1. Open and close force analysis of current sash system
  2. Vacuuming and cleaning top of fume hood
  3. Removal of all miscellaneous debris
  4. Cleaning sprockets and chains with special solvent and purging with pressurized air
  5. Lubrication of sprockets and chains with custom synthetic oil
  6. Lubrication of all extension slides – if part of the guide system
  7. Adjustment of sashes and weights for proper movement and alignment
  8. Recommendations will be made as to replacement parts if necessary

Notes:

  1. Our recommendation is to have this program completed 2 times a year
  2. This work can be completed on the hood with no affect on the work being done in the hood
  3. No mechanical disconnects are needed to perform this work

FLEX-A-SCOPE, A STACKABLE ALUMINUM LABORATORY MANIFOLD

File0001

Manifold as used in a laboratory environment is defined as a pipefitting with several lateral outlets for connecting one pipe with others. In various lab settings, it is necessary to utilize manifold as a means of carrying building services such as nitrogen, oxygen, water, compressed air, vacuum and carbon dioxide to individual lab spaces from a remote storage area.  This is necessary for two reasons: First, it is hazardous to locate gas cylinders in a laboratory area, and secondly, it is a waste of valuable floor space. Well designed gas delivery systems provide safety, efficiency, aesthetics and cost-efficiency.

Flex-a-scope is a stackable, aluminum manifold that provides a safe, attractive delivery system for house services.

 

Flex 10

 

Flex-a-scope can be mounted vertically or horizontally on a wall or reagent shelf support, and even on the ceiling, depending on the building design. Each end and outlet is drilled and tapped, and can be capped for future use.

Flex-a-scope can be installed with open or closed brackets, staggered fittings, as well as other options to support individual requirements.

The result – an attractive, user-friendly work bench providing house services in a safe, efficient facility.

Phenolic Resin Countertops

WHAT ARE PHENOLIC RESIN COUNTER TOPS?

  Phenolic Resin is a plastic-like material formed from a chemical reaction between a carbon based alcohol and an aldehyde.  Aldehydes are organic chemicals with the     structure of R-CHO, which is a carbon double bonded to an oxygen center (a formyl group), which in turn is bonded to hydrogen and a side chain.

. In the mid 1900’s this material was mixed with wood fibers and heated to high temperatures, forming a strong plastic-like polymer. This was used to make handles for cooking utensils and ovens, as well as other household items, such as the phone below. This early plastic was called Bakelite. phenolic-resin-image

  Today, phenolic resin is made by compressing many layers of paper and impregnating them with the liquid resin under high heat and pressure conditions. The result is a relatively light weight, chemical resistant product that can be fabricated into tops, cabinets, and shelving.

Phenolic resin countertops are often used today in place of the traditional black epoxy resin tops in hospitals, restaurants, schools and many laboratories.

Saving Energy with Smart-Sash®

Fume hoods are essential components of research facilities, whether they be pharmaceutical, medical, industrial, biotechnical or education-based. They serve multiple purposes, the most important being to protect workers in the lab from breathing harmful vapors. Unfortunately safety comes at a price, and it has been estimated that one fume hood running for 24 hours a day uses as much energy as two single homes.

In order to maximize energy conservation and increase laboratory safety, Jamestown Metal Products has developed Smart-Sash®. This is a fully automated, programmable system which opens and closes the sash completely hands free. Whenever a researcher enters the designated field of operation in front of the fume hood, the sash will automatically open, and likewise will close 15 to 20 seconds after technician steps away. This eliminates the uncontrollable human factor, optimizing safety and efficiency.

 

 

Features include:

  • Electronic gear motor coupled to the chain and sprocket sash counterbalance system.
  • Direct drive to sash chain allows smooth uninterrupted up and down motion.
  • Sash closes within 20 seconds after operator leaves the front of the hood.
  • Able to be retrofitted on JMP or non-JMP bench hoods.
  • Operator can stop the sash opening at any time and re-position manually.
  • Meets ANSI/AIHA Z9.5-2003 specifications.
  • Minimizes exposure by returning the sash to the closed position when not in use.
  • Low volume audible pulses alert operator of sash closure.
  • Prevents cross contamination between hoods.
  • Up to $2,561 annual savings per hood.
  • Aerodynamic sash handle allows for the containment of harmful fumes during rapid sash movement.

    From organic chemistry experiments in a university setting, to drug synthesis in a pharmaceutical lab, Smart-Sash® is unparalleled in its increased safety, efficiency and energy conservation.
