FRL ANSWERS --
Answer 1:
Yes. With the bowl removed, hold the bowl with the bottom end up. The manual drain can be removed by turning the drain stem clockwise, (looking at the bottom of the bowl) until the drain drops out. Hold the bowl upright and drop the auto drain into the bowl and through the hole in the bowl. Grasp the stem and turn the auto drain counterclockwise, (looking at the bottom of the bowl) until the drain is finger tight.
Answer 2:
Basic information one should know is pipe size, inlet pressure (PSIG), flow (SCFM) and for regulators, the regulated pressure range. The temperature of the air stream and the ambient temperature, and whether or not any incompatible chemicals, solvents, vapors, or oils are present in the atmosphere or air stream is also important. One can estimate flow by adding the usage of all the machinery being supplied downstream (point of use). It is always good to be a little conservative, and add flow for users who might occasionally blow down equipment, or otherwise exhaust air for some reason. You can also size products by using the performance charts that are in each product section of our catalog. It is always good design to have no more than a 2-3
PSI pressure drop, at maximum rated flow, with a clean element. Oversizing filters costs you a little extra in purchase price; undersizing filters costs you in wasted energy (high pressure drop) over the entire life of the filter in the system!
Answer 3:
The injection lubricator should be used in any application where the lubricator cannot be mounted within 10-12 feet of the application or if the air flow is intermittent. The injection lubricator is best suited for applications where the air flow is intermittent. The pulse generator option allows the injection lubricator to be used in a steady air flow and the counter option allows for use when the cycle rate is too often. The injection lubricator can place a drop of oil directly in the inlet of a tool each time it cycles, by the use of a capillary tube routed inside or outside the airline.
Answer 4:
A relieving regulator will exhaust downstream air when the secondary pressure rises above the set pressure of the regulator. This could happen from some piece of machinery inducing a back pressure in the system or from merely turning down the pressure of the regulator (regulator will relieve while adjusting to a lower pressure). A non-relieving regulator will not exhaust downstream air regardless of secondary pressure.
Answer 5:
The DP indicators measure the outlet pressure from the filter to the inlet pressure. A spring will move the green portion of the indicator to red when the differential pressure between inlet and outlet reaches 7
PSI. This differential indicates that it is time to replace the element.
Answer 6:
By going to the page in our product catalog where the filter is shown. On the page with the performance charts, you will find replacement element kits listed. You can also find this information listed on the Installation and Maintenance Sheet for your filter. And, refer to the chart following the next question.
