过滤调节器：
在保护敏感的下游设备时，我们认为气压过滤器调节器是至关重要的空气处理设备。过滤器调节器的目的是使空气管道中的水分和颗粒物全部稀薄，同时将气压降低到设定值。当要保护昂贵的实验室设备，阀门定位器或I / P传感器时，这是至关重要的。此处的调节原理与所有气压调节器的调节原理相同。但是，我们迫使供应空气通过尺寸为40或5微米的烧结聚乙烯过滤器，以过滤掉供应空气中的水分和非常小的颗粒。从空气中滤出的所有物质都被收集在滴水井中，可以在流体碰到特定点时手动排出或自动排出。 ControlAir (中文名：康气通）的过滤器调节器均具有1英寸水柱的灵敏度，并可用铝或不锈钢制成，并有减压阀和非减压阀。

通用调压阀：
当成本比精度高时，通用稳压器是更合适的选择。我们看到通用调节器经常在OEM应用中使用。尽管我们大多数精密调节器对1/8”水柱敏感，但我们的通用调节器（如以下400型）对1”水柱或0.036 PSI敏感。但是，由于这些单元的设计目的不是为了排出少量空气，所以使用通用调节器时，通常会减少空气消耗。这些类型的气压调节器在流体动力行业以及过程控制仪表和面板中得到了广泛的应用。由于它们更经济，因此它们是调节单个服务线的好单元，而不是总商店航空公司，这将需要一个具有更大流量限额的单元

Filter Regulators:
We consider air pressure filter regulators to be a vital air preparation device when it comes to protecting your sensitive downstream equipment. The purpose of a filter regulator is to  lean the air line of moisture and particulates all while reducing air pressure to a setpoint. This is essential when it comes to protecting expensive lab equipment, valve positioners, or I/P transducers.  The regulating principles are the same here as they are for all air pressure regulators. However, we are forcing the supply air through a sintered polyethene filter, either 40 or 5 microns in size, to filter out moisture and very small particulates from the supply air. Everything that is filtered out of the air is captured in a drip well and can be either manually drained or automatically drained whenever the fluid hits a certain point. ControlAir (中文名：康气通）’s filter regulators all have a sensitivity of 1” water column and are available in aluminum or stainless steel, as well as relieving or non-relieving.

General Purpose Regulators:
A general purpose regulator is a more appropriate selection when cost is a priority over precision. We see our general purpose regulators often used in OEM applications.  While most of our precision regulators are sensitive to 1/8” water column, our general purpose regulators, like the Type 400 below, are sensitive to 1” water column or 0.036 PSI. Since these units are not designed to bleed a small amount of air however, you will see generally less air consumption when using a general purpose regulator. These types of air pressure regulators see a lot of use in the fluid power industry as well as process control instrumentation and panels. Since they are more economic, they make good units to regulate individual service lines rather than the main shop airline, which would require a unit with a greater flow allowance.
