The Microfast® line includes residential, quick-response commercial and extended coverage models. Microfast sprinklers come in a variety of thread and orifice sizes and are available in chrome, natural or bright brass, black, white or Navajo white with color-matched flat or special adjustable escutcheons. By employing special coatings, black (Teflon) and white (polyester) Microfast sprinklers not only provide decorative solutions, they offer an increase in corrosion resistance as well. Microfast sprinklers employ a slender bulb element (135°F, 155°F, 175°F, 200°F, and 286°F - residential is 155°F and 175°F only) that is much small than other sprinkler actuating mechanisms, yet as resistant to damage as any available sprinkler. This bulb makes the Microfast several times more sensitive than standard sprinklers. Microfast standard spray sprinklers are available in upright, pendent, and sidewall models, and the Extended Coverage Microfast in pendent and sidewall models.
