Two Hands Anti Tie Down Pneumatic Logic
Product Specifications
Features
Description
A two hand anti tie down logic is used when both operator hands are required to actuate a pneumatic system. This is a control box is capable of two hand anti tie down logic. This control box is compact and can be readily incorporated into any pneumatic system - mounting holes are also included. There are 3 input fittings and one output fitting:
1. Supply Air: 1/4 inch push to connect fitting
2. Input Signal 1: 22mm push button
3. Input Signal 2: 22mm push button
4. Output Air: 1/4 inch push to connect fitting
Pneumatic only - Does not require electricity. Supply the pressure line in the input, and output pressure is generated when both buttons are pressed simultaneously.
Anti tie down - both push buttons must be actuated simultaneously in order to generate an output signal.
Anti Repeat - both buttons must be released before another cycle can be initiated.
Anti Bridging - this control box is designed so that the operator must use both hands in order to initiate an output signal.
Meets or exceed all applicable OSHA Standards of this date including 1910.217(6), 1910.217(b)(13).
Meets ANSI B11 Standards as they apply to the operation of pneumatic systems.
Products Quality
Our Acrylic Vacuum Chambers come with a one year warranty and our quality promise. The Chambers are robust and designed to be operated frequently for several years and are the result of years of continuous improvement, research, design, and development.
The ruggedized chamber walls are fabricated through our acrylic interlocking technology using specifically formulated vacuum glue-epoxy. Our adhesion expertise is one of our many trade secrets we utilize to build our chambers. This commitment to engineering excellence results in our acrylic vacuum chambers being so durable where issues such as deflection, beveling, collapsing, or wall separation are completely eliminated.
The 3 ports on this chamber are connected through threaded Aluminum Ports to a KF25/NW25 vacuum bulkhead fitting located on the acrylic wall or lid. This means that we do not thread into acrylic; hence the risk of cracking/crazing of threads over time is non-existent. Additionally, our acrylic chamber can easily be coupled to a KF25/NW25 vacuum connection.
We offer an amazing vacuum spec on this chamber at 0.075 Torr (75 micron) which impressively places this chamber into medium vacuum category. The Vacuum loss rate (leak tightness) of this chamber is 50 microns per minute initially which later decreases and then levels off. Therefore, this chamber will not lose more than 5.25 Torr (0.2 inHg) in 24 hours.
We would also like to acknowledge and thank many of our satisfied customers who over the years have helped us build better chambers by providing us with invaluable cooperation and feedback. Their inputs not only helped us improve on already fantastic chambers we were building for them, they have also improved the product quality for our future customers.
Please feel contact us with any questions you may have.

Frequently Asked Questions
1. What kind of vacuum pump should I use with this unit?
Any rotary vein pump (single stage or two stage) up to 7.5 CFM is ideal. A higher CFM pump will pull a faster desired vacuum level as opposed to a lower CFM pump. Keep in mind that the vacuum rating of this chamber is 0.075 Torr (75 micron), therefore any vacuum pump that has a vacuum rating of 0.075 Torr (75 micron) or less will work fine. We go in great detail explaining how to select a proper pump for your chamber, the article can be found here: Selecting a Proper Vacuum Pump for your Acrylic Vacuum Chamber
2. What is the strongest vacuum that can be achieved with this unit?
The vacuum level depends on the type of vacuum pump you plan to use with the unit. This chamber is rated at 0.075 Torr (75 micron), therefore a proper pump will enable a 0.075 Torr (75 micron) vacuum.
3. Do I need anything else in order to use this chamber?
The vacuum valve port is an 1/4 in NPT sized port, depending on how you would like to connect your vacuum pump to the chamber, you will have to purchase a hose (preferably vinyl reinforced), a barb (1/4 NPT male end to barb), and a couple of hose clamps from your local hardware store. However, if you contact us after you have placed your order and before we have shipped it, we will include a barb, two hose clamps, and about 5 feet reinforced vinyl hose as a customer courtesy.
4. Will the material I am degassing expand during operation?
Yes. To determine how much you can effectively degass at a time, we recommended that you first experiment with small amounts of material/liquids.
5. Can this chamber be heated?
Yes, many of our customers routinely heat these chambers. The chamber can safely be heated up to 110 F (43 C), in excess of that the user assumes all risk.
5. How come your chambers are better and cheaper than anything else out there? What`s the deal here?
It`s called vertical integration. We buy the acrylic material straight from the wholesaler, build-to-order the acrylic chamber in house, and sell it ourselves, effectively eliminating two middle men and a huge warehouse during this process. Not only are resources saved doing this, we also have full control over the design and manufacturing process meaning that you get the best acrylic vacuum chamber at the lowest cost and lead times.
