Airpulse PK2

Product Details

The Airpulse PK2 wheelchair cushion system is our most dynamic cushion system. It was designed to be the most advanced solution to help prevent and heal pressure ulcers.

The patented Airpulse PK2 is an automatic pressure relieving device that ensures adequate pressure relief and blood flow. Alternate cells of the cushion are automatically inflated and deflated to the desired firmness on an adjustable timed cycle. This action changes pressure contact points and stimulates circulation to the compressed tissue. Circulation is maintained to all areas of the posterior so the primary cause of skin breakdown is eliminated.

Each and every Airpulse PK2 wheelchair cushion system is custom made to order to address the client's specific needs. We have taken on many challenging situations with remarkable results. Clinical case results and customer feedback have proven this product to be effective and doctors frequently recommend the Airpulse PK for use by their patients.

Standard Battery Model: powered from its own rechargeable battery source, it will operate for up to 40 continuous hours per charge.

The Airpulse PK wheelchair cushion system is preprogrammed and ready to operate when delivered. The system includes the custom made cushion, cushion cover, controller with cover, battery charger (if applicable), and a one year warranty. See Product Diagram PDF for details.

The Cushion

The Airpulse PK2 cushion is made of soft but durable Neoprene (no latex) and has a series of air cells. The cells are shaped to fit the contours of the body for comfort and support. They are also reinforced with internal air bladders to ensure long service life. (See Durability Test Results) The two ischial air cells are attached to the cushion base with Velcro enabling them to be easily repositioned if needed. Alternating air cells are capable of being inflated and deflated at different pressure levels and for varying times for maximum pressure relief where and when you want.

Because every Airpulse PK2 wheelchair cushion system is custom made, the cushion can be built to whatever size works best for the client's needs. In other words, no standard sizes, but rather the correct size. The Airpulse PK cushion can support weights in excess of 400 pounds and bariatric sizes can be made. Cushion sizes larger than 22" wide or 22" deep have an additional fee.

If the client has a current pressure sore, we may customize the cushion with a convertible cell so there will be virtually zero upward pressure directly under the sore until complete healing is achieved (see Pressure Maps). Once the sore is healed, the cell is integrated back into normal operation in just seconds.

Even with the specialization involved in custom building every system, the product is typically built and shipped within a few days of receipt of order.

The Controller

The control module of the Airpulse PK2 provides the mechanism to operate the cushion's unique air cell configurations. The controller contains the micro-processor, control panel, air pump and battery (if applicable). It is portable, quiet, weighs less than two pounds and the easy-mount cover can be fastened to the armrest, back, or other parts of the chair. Depending on the model, the controller is powered either by an internal battery or directly from the powerchair batteries.

The controller gives the user or caregiver a wide range of firmness and cycle time settings, and adjustments can be made with the touch of a button - making it fully adjustable to adapt to the client's future needs. The two sets of air cells can be set to completely different inflation/deflation cycle times to address pressure relief needs for different posterior locations.

Optional Accessories

All Airpulse PK wheelchair cushion systems include customized cushion with stretch cover, pre-programmed controller with cover, battery charger with the Battery or Hybrid Models, and a one year manufacturer’s warranty. Aquila does offer the following optional accessories:

Customized Solution

The Airpulse PK is not an “off the shelf” product. Each Airpulse PK cushion system we build is tailored to match the specific needs of the individual client. We have years of experience in designing the most appropriate systems for difficult seating situations. We gather information on the client such as weight, location of any existing and past history of any pressure sores, the type of chair used by the client, and any special situations such as compensating for pelvic lean, high level amputations, MS patient with severe pelvic obliquities and patients with acute Stage IV pressure sores. Then we program the controller and build the cushion for optimal effectiveness. The Airpulse PK system has also helped reduce recovery time for post flap surgery patients. See our Customization Scenarios for examples.


The Airpulse PK has a low pressure audible and visual alert. The cushion will not deflate if the battery should become fully discharged or the unit is turned off. The cells also have foam insert to guard against bottoming out in the unlikely event that the cushion should become damaged and lose air.
