The present discloses a dehumidifier apparatus for emitting dehumidified air to an air tank in the posterior stage with the highest pressure even in the case that the compressed air pressure could have diminished in an important manner. A dehumidifier apparatus of hollow membrane of filter which possesses (a) hollow fiber membranes that make compressed air supplied from one end to the interior to flow and at the same time to discharge dampness from said compressed air to the other end as dehumidified air; (b) a reflux route that makes that a portion of the dehumidified air expelled from said membranes of hollow fiber flow again to the exterior of said membranes of hollow fiber as purged air; and (c) a variable limiter provided in said reflux route that increases or decreases the aperture-closure volume according to the increment of the air pressure diminishment that flows through the interior of said membranes of hollow fiber.
