Add Air Fume Hoods


The LOC Airfoil Add Air Fume Hood provides added economy through the use of a front mount “add air plenum” that can supply up to 70 percent of the total hood air volume required from an outside source.


Design Elements:
  • Built-in bypass works to maintain a relatively constant face velocity at any sash position
  • Front mounted add air plenum utilizes diffusers and louvers to allow a uniform flow of supply air
  • Provides up to 70% of the overall air volume requirements
  • Equipped with a full view sash providing an unobstructed view of the hood interior
  • Sash is 7/32” laminated safety glass with full width flush PVC pull and spring loaded sash stop
  • Counterweight provides a one finger sash operation
  • Includes audible LOC200 airflow monitor for safety
  • Hood entrance is framed with inward-angled members to minimize turbulence and provide smooth air movement in hood at face velocities ranging from 60 to 150 FPM
  • Stainless steel airfoil allows 1” of airflow across the work surface when sash is in the closed position
  • Double wall construction for ease of routing plumbing/electrical lines
  • Standard “Resin-Chem” interior liner with removable access panels on both sides
  • Removable exterior side panels
  • Maximum width, two tube fluorescent light fixture complete with tubes is provided
  • Light is mounted above a sealed safety panel keeping corrosive fumes and hazardous vapors isolated
  • Tube lights can easily be replaced through the top front

High Performance Fume Hoods


LOC's Trilogy model High Performance Fume Hoods are designed to provide maximum personal protection at half the energy costs of a conventional fume hood.
High Performance fume hoods not only save the lab money by reducing the volume of air that needs to be conditioned and exhausted, it also reduces the size of the HVAC equipment saving on the original capital investment.

Although energy efficiency was the goal of the design, one of the main reasons to purchase a high performance fume hood is safety.

Design Elements:

  • Engineered baffle system for proper air distribution and constant face velocity.
  • Rounded corners at hood entrance for smooth air flow with less turbulence.
  • Aerodynamic sash pull.
  • Flush sill containment trough with directional vanes and white Plas-Cote finish for durability and chemical resistance.
  • Cord pass through allows the sash to fully close without interference from appliance cords.
  • Safety bar at the lower entrance of the hood provides the operator a personal safety barrier.
  • 35" high viewing area
  • White Resin-Chem interior with vapor proof T8 fluorescent light for bright interior viewing.
  • Full view sash frame with top hung horizontal sash panels provide 27 ½” high interior access.
  • Optional 18" vertical opening with a keyed sash stop to access a 27 ½” set-up position.

Electromechanical Relays


Electromechanical Relays1.gif
A few uses for relays are:
1. Control a larger/smaller voltage/current with a smaller/larger voltage/current. 2. Holding or Latch circuit to “capture” a momentary input signal 3. As building blocks in basic logic circuits 4. Isolate the input circuit from the output circuit
The Holding Circuit (or Latch) has commonly been used in MP to turn on a device with a momentary signal. A brief electrical pulse actuates a holding circuit which keeps power applied after the pulse has ended. For discussion, we’ll use a ball rolling into an elevator to be raised to the top of the device. As the ball enters the elevator, it depresses a lever closing normally open contacts of a switch mounted on the floor under the elevator. As the elevator rises, it lifts the ball off the switch, releasing the lever and allowing the contacts to open. The drawing below shows the basic holding/latch circuit. To simplify the diagram, both the relay coil and Device Under Control use the same battery.
Electromechanical Relays2.gif
First Diagram: Electricity cannot flow to the Elevator (Device Under Control) because of the normally open contacts of switch (S1) and the relay. Second Diagram: The ball rolls into the elevator, closing S1, energizing the relay coil and starting the elevator. Third Diagram: The elevator lifts the ball off S1, allowing its contacts to open. Normally this would break the circuit and the elevator would stop; however, the closed relay contacts continue supplying current to both the relay coil and the elevator.
This works great, but sooner or later the elevator reaches the top. If it continues to run, it could cause physical damage or waste energy from the batteries. Our next circuit addresses the problem.
Electromechanical Relays3.gif
In this circuit we’ve added a normally closed switch (S2). Its purpose is to stop the elevator when it reaches the upper limit of its travel.
First Diagram: The ball has just rolled into the elevator closing S1 and starting the elevator. Second Diagram: As the elevator rises, S1 opens, but the latch circuit keeps the elevator on. Third diagram: When the elevator reaches the top, it opens the normally closed switch S2, de-energizing the relay and stopping the elevator. Since the relay contacts are now open, closing S2 will not start the elevator again.
A switch that prevents a device from exceeding specified parameters is called a “limit switch”, regardless of what type it is. Lever switches and magnetic reed switches are particularly well suited in these applications.
The Loop-Back Circuit And finally, the last circuit! Sometimes it’s desirable to have several devices in series. The circuit below shows how each device can turn off the preceding device. This is sometimes called a “loop-back” circuit.
Electromechanical Relays4.gif
Switches S1, S2 and S3 and the normally open relay contacts prevent any of the devices from running.
Electromechanical Relays5.gif
A mechanical action closes switch S1, energizing the 1st latch, starting the 1st device.
Electromechanical Relays6.gif
1st device continues operation, even though S1 has opened.
Electromechanical Relays7.gif

The 1st device completes, closing S2, energizing the latch, turning off the 1st device and starting the 2nd device.

Electromechanical Relays8.gif
2nd device continues to operate, even though S2 has opened.
Electromechanical Relays9.gif 2nd device completes its action closing S3, energizing the 3rd latch, turning off the 2nd device and starting the 3rd device.
Electromechanical Relays10.gif

3rd device continues to operate, even though S3 has opened.


3rd device completes its action, openings S4, releasing the latch and stopping the 3rd device. Since none of the relays are latched, none of the devices will operate, even if S4 closes again.
